Subject: update-utmp: shorten comm on boot/shutdown
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b8968c492108506952ab2748c4a44ce32fc9477c;p=thirdparty%2Fsystemd.git

update-utmp: shorten comm on boot/shutdown

audit_log_user_comm_message from libaudit 4.2 rejects comm arguments
that exceed the kernel's comm limit of 15 characters with EINVAL. The
hard-coded "systemd-update-utmp" exceeds this by 4 characters. Shorten
it to "update-utmp" instead.
