manager_sync_bus_names() function retrieves the dbus names
and compares it with unit bus names. It could be right
after the list is retrieved, the dbus peer is disconnected.
In this case it is really not an ERROR print if
sd_bus_get_name_creds() or sd_bus_creds_get_unique_name()
fail.
This complements existing functionality of setting variables
through 'systemctl set-environment', the kernel command line,
and through normal environment variables for systemd in session
mode.
.mount units coming from /proc/self/mountinfo file are
unmounted after local-fs.target is reached during shutdown.
Problem: .mount units popping up in mountinfo file are
added to systemd without any dependency. For that reason,
they are the first one to be unmounted during shutdown.
Whichever program mounted the file system deserves a
chance to also unmount it. This patch ensures that
/proc/self/mountinfo units will be unmounted after
local-fs.target during shutdown (if they haven't been
unmounted already)
If firmware file is not found in the file system, udev
terminates firmware loading. This is not the case if
firmware file exists in the file system but doesn't have
any data in it.
