[arch-general] Can pam_systemd_home.so functionality be split into a separate package to prevent cluttering the logs?

[David C. Rankin]

Archdevs,

  Just as postfix is being split to separate non-default backends into
separate packages, can pam_systemd_home.so functionality be split out into a
separate package. The problems caused by this disabled part of pambase is
discussed here:

https://bbs.archlinux.org/viewtopic.php?pid=1952091

Even though the service is disabled, it fill the journal with entries every
time sudo is invoked. For example, every time sudo is used with journalctl,
you get 5-long lines of nonsense:

Jan 26 03:17:42 phoinix dbus-daemon[363]: [system] Activating via systemd:
service name='org.freedesktop.home1' unit='dbus-org.freedesktop.home1.service'
requested by ':1.19' (uid=0 pid=5293 comm="sudo journalctl --no-pager --full -f ")
Jan 26 03:17:42 phoinix dbus-daemon[363]: [system] Activation via systemd
failed for unit 'dbus-org.freedesktop.home1.service': Unit
dbus-org.freedesktop.home1.service not found.
Jan 26 03:17:42 phoinix sudo[5293]: pam_systemd_home(sudo:account):
systemd-homed is not available: Unit dbus-org.freedesktop.home1.service not found.
Jan 26 03:17:42 phoinix sudo[5293]:    david : TTY=pts/0 ; PWD=/home/david ;
USER=root ; COMMAND=/usr/bin/journalctl --no-pager --full -f
Jan 26 03:17:42 phoinix sudo[5293]: pam_unix(sudo:session): session opened for
user root(uid=0) by david(uid=1000)

  Why not let the very few that will ever want pam_systemd_home install that
package and enable the service rather than allowing a disabled server to
clutter the logs every time sudo is used and forcing folks that don't want the
noise from a disable package to set:

  NoExtract=usr/lib/security/pam_systemd_home.so

just to get rid of the unnecessary messages.
https://bugs.archlinux.org/task/65819 is referenced in the discussion.

  If nothing else, have NoExtract set by default and add a wiki entry about
removing NoExtract and reinstalling systemd for the few that want it?
