2015-11-11execute: Add new PassEnvironment= directiveFilipe Brandenburger
This directive allows passing environment variables from the system manager to spawned services. Variables in the system manager can be set inside a container by passing `--set-env=...` options to systemd-spawn. Tested with an on-disk test.service unit. Tested using multiple variable names on a single line, with an empty setting to clear the current list of variables, with non-existing variables. Tested using `systemd-run -p PassEnvironment=VARNAME` to confirm it works with transient units. Confirmed that `systemctl show` will display the PassEnvironment settings. Checked that man pages are generated correctly. No regressions in `make check`.
2015-11-11networkd: IPv6 router discovery - follow IPv6AcceptRouterAdvertisemnt=Tom Gundersen
The previous behavior: When DHCPv6 was enabled, router discover was performed first, and then DHCPv6 was enabled only if the relevant flags were passed in the Router Advertisement message. Moreover, router discovery was performed even if AcceptRouterAdvertisements=false, moreover, even if router advertisements were accepted (by the kernel) the flags indicating that DHCPv6 should be performed were ignored. New behavior: If RouterAdvertisements are accepted, and either no routers are found, or an advertisement is received indicating DHCPv6 should be performed, the DHCPv6 client is started. Moreover, the DHCP option now truly enables the DHCPv6 client regardless of router discovery (though it will probably not be very useful to get a lease withotu any routes, this seems the more consistent approach). The recommended default setting should be to set DHCP=ipv4 and to leave IPv6AcceptRouterAdvertisements unset.
2015-11-11journalctl: make --rotate synchronous, tooLennart Poettering
Of course, ideally we'd just use normal synchronous bus calls, but this is out of the question as long as we rely on dbus-daemon (which logs to journald, and thus cannot use to avoid cyclic sync loops). Hence, instead, reuse the wait logic already implemented for --sync, and use a signal in one direction, and a mtime watch file for the reply.
2015-11-11journalctl: add new --sync switch for syncing the journal to diskLennart Poettering
With this new "--sync" switch we add a synchronous way to sync everything queued to disk, and return only after that's complete. This command gives the guarantee that anything queued before has hit the disk before the command returns. While we are at it, also improve the man pages and help text for journalctl a bit.

Remove snapshot unit type
2015-11-10Remove snapshot unit typeZbigniew Jędrzejewski-Szmek
Snapshots were never useful or used for anything. Many systemd developers that I spoke to at systemd.conf2015, didn't even know they existed, so it is fairly safe to assume that this type can be deleted without harm. The fundamental problem with snapshots is that the state of the system is dynamic, devices come and go, users log in and out, timers fire... and restoring all units to some state from the past would "undo" those changes, which isn't really possible. Tested by creating a snapshot, running the new binary, and checking that the transition did not cause errors, and the snapshot is gone, and snapshots cannot be created anymore. New systemctl says: Unknown operation snapshot. Old systemctl says: Failed to create snapshot: Support for snapshots has been removed. IgnoreOnSnaphost settings are warned about and ignored: Support for option IgnoreOnSnapshot= has been removed and it is ignored http://lists.freedesktop.org/archives/systemd-devel/2015-November/034872.html

2015-11-10core: accept time units for time-based resource limitsLennart Poettering
Let's make sure "LimitCPU=30min" can be parsed properly, following the usual logic how we parse time values. Similar for LimitRTTIME=. While we are at it, extend a bit on the man page section about resource limits. Fixes: #1772

2015-11-10man: describe the reason why runlevels are obsoleteZbigniew Jędrzejewski-Szmek
Put it at the top of the file, where it's hard to miss. Also add the mapping of runlevel → target because since it is now static. I'm not adding runlevel(7), because we do not want to make obsolete stuff even more prominent.

2015-11-06core: support IEC suffixes for RLIMIT stuffKarel Zak
Let's make things more user-friendly and support for example LimitAS=16G rather than force users to always use LimitAS=16106127360. The change is relevant for options: [Default]Limit{FSIZE,DATA,STACK,CORE,RSS,AS,MEMLOCK,MSGQUEUE} The patch introduces config_parse_bytes_limit(), it's the same as config_parse_limit() but uses parse_size() tu support the suffixes.

2015-11-02man: Drop "internally," which is misleadingDavid Strauss
The existing text misleads readers into thinking how the notify socket protocol is "internals" and that they can only use the functions. However, the socket is part of the Interface Stability Promise. So, we should drop "internally" from the description so the man page both indicates both how the functions work and how one would talk to the socket directly.

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...

This option specifies the label to assign the root of the file system if it lacks the Smack extended attribute. Note that this option will be ignored if kernel does not support the Smack feature by runtime checking.

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.
