Public bug reported:
I have a some chown failures in /var/log/syslog, that come from the many
sssd-*.service files' ExecStartPre commands:
Example for the sssd-sudo service, started by sssd-sudo.socket:
# systemctl cat sssd-sudo.service | grep chown
ExecStartPre=-/bin/chown root:root /var/log/sssd/sssd_sudo.log
# grep chown /var/log/syslog
Sep 3 17:26:27 g-adclient1 chown[880]: /bin/chown: cannot access
'/var/log/sssd/sssd_sudo.log': No such file or directory
Sep 3 17:32:03 g-adclient1 chown[1118]: /bin/chown: cannot access
'/var/log/sssd/sssd_sudo.log': No such file or directory
Sep 3 17:34:58 g-adclient1 chown[1158]: /bin/chown: cannot access
'/var/log/sssd/sssd_pam.log': No such file or directory
Sep 3 17:34:58 g-adclient1 chown[1162]: /bin/chown: cannot access
'/var/log/sssd/sssd_pac.log': No such file or directory
They are not fatal, as the commands are prefixed with "-", but generate
this noise the first time each service is started (they are socket-
activated).
All but sudo seem to create a log file eventually, so the next time they
start, the file will be there and chown will work, but sudo doesn't seem
to create one in the default config, so this error will repeat.
The service file comes like this from upstream:
ExecStartPre=-/bin/chown @SSSD_USER@:@SSSD_USER@ @logpath@/sssd_sudo.log
There is a configure build-time option to run sssd as another user
aparrently (which debian and ubuntu do not use):
--with-sssd-user=<user> User for running SSSD (root)
That is what sets @SSSD_USER@ ultimately, so I guess the chown is really
there for when the user is not root.
** Affects: sssd (Ubuntu)
