First, rename root-fs.target to initrd-root-fs.target to clarify its usage.
Mount units with "x-initrd-rootfs.mount" are now ordered before
initrd-root-fs.target. As we sometimes construct /sysroot mounts in
/etc/fstab in the initrd, we want these to be mounted before the
initrd-root-fs.target is active.
initrd.target can be the default target in the initrd.
(normal startup)

Instead of using local-fs*.target in the initrd, use root-fs.target for
sysroot.mount and initrd-fs.target for /sysroot/usr and friends.
Using local-fs.target would mean to carry over the activated
local-fs.target to the isolated initrd-switch-root.target and thus in
the real root. Having local-fs.target already active after
deserialization causes ordering problems with the real root services and
targets.
We better isolate to targets for initrd-switch-root.target, which are
only available in the initrd.

This pulls in remote-fs-pre.target if remote-fs.target is needed.
Previously remote-fs-pre.target was not active, if no remote fs was
mounted from /etc/fstab. So, every manual remote fs mount was ordered
against the inactive remote-fs-pre.target and umount.target.
Because remote-fs-pre.target was not active, the remote fs was umounted
at umount.target time, which was too late (network already down).
Now remote-fs-pre.target is active, even if no remote fs is mounted.
On shutdown it is deactivated in the correct order and all manual remote
fs mounts also.

The udevadm utility is needed during early boot, so move it to
rootbindir to support split-/usr configurations.
|
|
Instead use @bindir@ for udevadm and @rootbindir@ for systemctl.

This will:
* mount all configured filesystems (typically the rootfs on /sysroot)
* reload the configuration to pick up anything from the mounted fs (typically
/sysroot/etc/fstab)
* mount any newly configured filesystems (typically /usr on /sysroot/usr, if
applicable)
* shut-down and clean-up any daemons running in the initramfs (typically udevd)
* switch-root to /sysroot and start the real init
For an example of what files should be included in an initramfs based on this

Sometimes it is useful to look at them, and they don't take
up any significant amount of space. Keeping them also avoids
the message about files being removed at the end of make
run.

We no longer allow early-boot init scripts, however in late boot the
syslog socket and local mounts are established anyway, so let's simplify
our dep graph a bit.
If $syslog doesn't resolve to syslog.target anymore there's no reason to
keep syslog.target around anymore. Let's remove it.
Note that many 3rd party service unit files order themselves after
syslog.target. These will be dangling dependencies now, which should be
unproblematic, however.

Systemd should not introduce any new facilities. Distributions which still
need to support their non-standard/legacy facilities should add them as
patches to their packaging.
The following facilities are no longer recognized:
$x-display-manager
$mail-transfer-agent
$mail-transport-agent
$mail-transfer-agent
$smtp
$null
This target is no longer available:
mail-transfer-agent.target

sushell makes much less sense than sulogin. If distros want to stick to sushell
they should patch this downstream.
|
|
Since rc-local is now enabled via the SysV compatibility we should only refer
to it based on that too.
|
|
This also drops automatic selection of the rc local scripts
based on the local distro. Distributions now should specify the paths
of the rc-local and halt-local scripts on the configure command line.

Frugalware are shipping their own .service file now, so stop shipping
it here.

specific
This was premarily intended to support the LSB facility $httpd which is
only known by Fedora, and a bad idea since it lacks any real-life
usecase.
Similar, drop support for some other old Fedora-specific facilities.
Also, document the rules for introduction of new facilities, to clarify
the situation for the future.

Environment=TERM=... has no effect on agetty who sets it by itself. To
really set TERM to a specified value, it has to be given on the command
line.

This makes the behaviour wrt. to rc[-.]local consistent between
various distributions supporting it.

Do not suggest to the user that commands can be issued before
logging in.
sulogin prints it own message, which mentions ^D, so there's no need
to repeat it here.

Since tmp.mount is a tmpfs this is not necesary, and should speed up boot marginally.

More often than not we enter emergency.service due to fsck failure, so
it makes sense to direct people to the journal to debug those.

This should make session termination more reliable, as D-Bus doesn't
have to be around anymore for this to succeed.

This minimal HTTP server can serve journal data via HTTP. Its primary
purpose is synchronization of journal data across the network. It serves
journal data in three formats:
text/plain: the text format known from /var/log/messages
application/json: the journal entries formatted as JSON
application/vnd.fdo.journal: the binary export format of the journal
The HTTP server also serves a small HTML5 app that makes use of the JSON
serialization to present the journal data to the user.
Examples:
This downloads the journal in text format:
# systemctl start systemd-journal-gatewayd.service
# wget http://localhost:19531/entries
Same for JSON:
# curl -H"Accept: application/json" http://localhost:19531/entries
Access via web browser:
$ firefox http://localhost:19531/

It is no longer possible to manually enable systemd-udev-settle.service,
so its only use is by legacy services explicitly pulling it in. It makes
sense for these services to also explicitly order themselves after
udev-settle.service, which makes After=basic.target redundant.
This should reduce the negative effect on boot-time of having to enable
legacy services such as lvm.service.
|
|
Legacy tool on-demand pull-in the settling, it should never run
by default, nothing orders against is anyway.

Use AC_PATH_PROG to try and locate the quotaon and quotacheck binaries,
falling back on hardcoded defaults when they can't be found.
|
|
In the initrd we don't need the flush service hence don't attempt to
pull it in.

It's time to get rid of prefdm. Distributions which still want to use
this should maintain this downstream, but it's probably better to just
provide proper units for the various display managers, like Fedora is
doing this, for example:
https://fedoraproject.org/wiki/Features/DisplayManagerRework
|
|
For 'modules-load=' and 'rd.modules-load=' to be effective,
systemd-modules-load.service must be started. It is currently
conditional on the existence of config files. Add the presence of the
cmdline parameters to the triggering conditions.

|
|
These services should be restarted as quickly as possible if they fail,
and the extra safety net of the holdoff time is not necessary.
