core: consider SIGTERM as a clean exit status for initrd-switch-root.service (#4713)
Since commit
1f0958f640b8717, systemd considers SIGTERM for short-running
services (aka Type=oneshot) as a failure.
This can be an issue with initrd-switch-root.service as the command run by this
service (in order to switch to the new rootfs) may still be running when
systemd does the switch.
However PID1 sends SIGTERM to all remaining processes right before
switching and initrd-switch-root.service can be one of those.
After systemd is reexecuted and its previous state is deserialized, systemd
notices that initrd-switch-root.service was killed with SIGTERM and considers
this as a failure which leads to the emergency shell.
To prevent this, this patch teaches systemd to consider a SIGTERM exit as a
clean one for this service.
It also removes "KillMode=none" since this is pretty useless as the service is
never stopped by systemd but it either exits normally or it's killed by a
SIGTERM as described previously.

units to start too early (before the ready notification).
Additionally, when RemainAfterExit=yes is used on a Type=notify service, the

After this commit, an unsuccessful exit of the main process of a Type=notify

in case RemainAfterExit=yes. Otherwise, when no ready notification has been

This essentially makes "systemd-nspawn --ephemeral" and "systemd-nspawn

still be slower on non-btrfs than on btrfs (simply because reflinking each file

for them.

namespace: simplify, optimize and extend handling of mounts for namespace
This changes a couple of things in the namespace handling:
It merges the BindMount and TargetMount structures. They are mostly the same,
hence let's just use the same structue, and rely on C's implicit zero
initialization of partially initialized structures for the unneeded fields.
This reworks memory management of each entry a bit. It now contains one "const"
and one "malloc" path. We use the former whenever we can, but use the latter
when we have to, which is the case when we have to chase symlinks or prefix a
root directory. This means in the common case we don't actually need to
allocate any dynamic memory. To make this easy to use we add an accessor
function bind_mount_path() which retrieves the right path string from a
BindMount structure.
While we are at it, also permit "+" as prefix for dirs configured with
ReadOnlyPaths= and friends: if specified the root directory of the unit is
implicited prefixed.
This also drops set_bind_mount() and uses C99 structure initialization instead,
which I think is more readable and clarifies what is being done.
This drops append_protect_kernel_tunables() and
append_protect_kernel_modules() as append_static_mounts() is now simple enough
to be called directly.
Prefixing with the root dir is now done in an explicit step in
prefix_where_needed(). It will prepend the root directory on each entry that
doesn't have it prefixed yet. The latter is determined depending on an extra
bit in the BindMount structure.

core: monitor the inotify file descriptor not the console one in acquire_terminal()
When waiting for the terminal to be release in acquire_terminal(), we
were monitoring the terminal fd instead of the inotify descriptor.
Therefore any write accesses would wake up the waiting process instead
of being wake up when the tty is closed only.

core: GC redundant device jobs from the run queue
In contrast to all other unit types device units when queued just track
external state, they cannot effect state changes on their own. Hence unless a
client or other job waits for them there's no reason to keep them in the job
queue. This adds a concept of GC'ing jobs of this type as soon as no client or
other job waits for them anymore.
To ensure this works correctly we need to track which clients actually
reference a job (i.e. which ones enqueued it). Unfortunately that's pretty
nasty to do for direct connections, as sd_bus_track doesn't work for
them. For now, work around this, by simply remembering in a boolean that a job
was requested by a direct connection, and reset it when we notice the direct
connection is gone. This means the GC logic works fine, except that jobs are
not immediately removed when direct connections disconnect.
In the longer term, a rework of the bus logic should fix this properly. For now
this should be good enough, as GC works for fine all cases except this one, and
thus is a clear improvement over the previous behaviour.
