2016-02-03nspawn: optionally run a stub init process as PID 1Lennart Poettering
This adds a new switch --as-pid2, which allows running commands as PID 2, while a stub init process is run as PID 1. This is useful in order to run arbitrary commands in a container, as PID1's semantics are different from all other processes regarding reaping of unknown children or signal handling.
2016-02-03nspawn: add new --chdir= switchLennart Poettering
Fixes: #2192
2016-01-28doc: improved wording in some placesJan Engelhardt
Avoid "mountpoint mounted" (word repetition), "queriable" (no match in m-w.com and dict.cc).
2015-11-12nspawn: add new --network-veth-extra= switch for defining additional veth linksLennart Poettering
The new switch operates like --network-veth, but may be specified multiple times (to define multiple link pairs) and allows flexible definition of the interface names. This is an independent reimplementation of #1678, but defines different semantics, keeping the behaviour completely independent of --network-veth. It also comes will full hook-up for .nspawn files, and the matching documentation.

2015-10-24man: let's enclose * in shell examples in ''Lennart Poettering
Technically, it's safer that way, since dnf is supposed to parse the "*", not the shell. It doesn't really matter too much in real life (as the expression is too complex), but let's better be safe than sorry, and make sure people won't file bugs about this...
2015-10-22man: also add --enablerepo=updates to dnf invocationZbigniew Jędrzejewski-Szmek
Without the updates repo, we are installing packages from the time that that version of Fedora was released. Normally, during the lifetime of the release most packages are updated, so most of the packages installed would be outdated, and the first update after installation would update a massive set of packages. Avoid all this by installing from the updates repo from the start.
2015-10-22man: remove --nogpg from dnf install command lineZbigniew Jędrzejewski-Szmek
Keys for previous and future Fedora distributions were added for the fedora-repos package recently: https://bugzilla.redhat.com/show_bug.cgi?id=1246701. There is no need to skip signature checking. Also, update to the latest and greatest and remove unnecessary quotes.
2015-09-22man: drop reference to yum from man pagesLennart Poettering
Apparently, yum is obsolete, and dnf is the new yum. Mention only dnf hence, and don't mention yum anymore.

2015-09-06nspawn: add new .nspawn files for container settingsLennart Poettering
.nspawn fiels are simple settings files that may accompany container images and directories and contain settings otherwise passed on the nspawn command line. This provides an efficient way to attach execution data directly to containers.
2015-08-28nspawn: add (no)rbind option to --bind and --bind-roEugene Yakubovich
--bind and --bind-ro perform the bind mount non-recursively. It is sometimes (often?) desirable to do a recursive mount. This patch adds an optional set of bind mount options in the form of: --bind=src-path:dst-path:options options are comma separated and currently only "rbind" and "norbind" are allowed. Default value is "rbind".

2015-08-05man: point nspawn --machine to machinectl search-pathRichard Maw
The --machine option used to describe searching for machines in /var/lib/machines, which is not the whole story, so let's link to where it's described in more detail.
2015-06-18man: revert dynamic paths for split-usr setupsTom Gundersen
This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
2015-05-28man: generate configured paths in manpagesFilipe Brandenburger
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

2015-05-13nspawn: rework custom mount point order, and add support for overlayfsLennart Poettering
Previously all bind mount mounts were applied in the order specified, followed by all tmpfs mounts in the order specified. This is problematic, if bind mounts shall be placed within tmpfs mounts. This patch hence reworks the custom mount point logic, and alwas applies them in strict prefix-first order. This means the order of mounts specified on the command line becomes irrelevant, the right operation will always be executed. While we are at it this commit also adds native support for overlayfs mounts, as supported by recent kernels.

2015-05-05man: nspawn is used in production these days, admit thatLennart Poettering
Previously, the man page suggested to only use nspawn for testing, building, and debugging things. However, it is nowadays used in production and used as building block for rocket, hence let's just admit that it's pretty much production ready.

2015-01-15nspawn,machined: change default container image location from ↵Lennart Poettering
/var/lib/container to /var/lib/machines Given that this is also the place to store raw disk images which are very much bootable with qemu/kvm it sounds like a misnomer to call the directory "container". Hence, let's change this sooner rather than later, and use the generic name, in particular since we otherwise try to use the generic "machine" preferably over the more specific "container" or "vm".
2015-01-13nspawn: add "-n" shortcut for "--network-veth"Lennart Poettering
Now that networkd's IP masquerading support means that running containers with "--network-veth" will provide network access out of the box for the container, let's add a shortcut "-n" for it, to make it easily accessible.
2015-01-13nspawn: add new option "--port=" for exposing container ports on the local hostLennart Poettering
This exposes an IP port on the container as local port using DNAT.

Also, when booting up an ephemeral container of / use the system hostname as default machine name. This way specifiyng -M is unnecessary when booting up an ephemeral container, while allowing any number of ephemeral containers to run from the same tree.

This adds --template= to duplicate an OS tree as btrfs snpashot and run it This also adds --ephemeral or -x to create a snapshot of an OS tree and boot that, removing it after exit.
2014-11-21nspawn: Add try-{host,guest} journal link modesMartin Pitt
--link-journal={host,guest} fail if the host does not have persistent journalling enabled and /var/log/journal/ does not exist. Even worse, as there is no stdout/err any more, there is no error message to point that out. Introduce two new modes "try-host" and "try-guest" which don't fail in this case, and instead just silently skip the guest journal setup. Change -j to mean "try-guest" instead of "guest", and fix the wrong --help output for it (it said "host" before). Change systemd-nspawn@.service.in to use "try-guest" so that this unit works with both persistent and non-persistent journals on the host without failing. https://bugs.debian.org/770275

2014-07-07man: add a mapping for external manpagesZbigniew Jędrzejewski-Szmek
It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?

2014-06-13os-release: define /usr/lib/os-release as fallback for /etc/os-releaseLennart Poettering
The file should have been in /usr/lib/ in the first place, since it describes the OS container in /usr (and not the configuration in /etc), hence, let's support os-release files in /usr/lib as fallback if no version in /etc exists, following the usual override logic. A prior commit already enabled tmpfiles to create /etc/os-release as a symlink to /usr/lib/os-release should it be missing, thus providing nice compatibility with applications only checking in /etc. While it's probably a good idea if all apps check both locations via a fallback logic, it is only necessary in the early boot process, as long as the /etc/os-release symlink has not been restored, in case we boot with an empty /etc.
