Package: hurd
Version: N/A
Severity: normal
Hi,
I found out why screen complains about /var/run/screen permissions. screen
runs as root.utmp, 02755, and expects utmp as its effective group id.
The following program fails:
main()
{
printf ("%i\n", getegid();
}
$ make getegid
$ ./getegid
0
$ chgrp root.utmp getegid; chmod 02755 getegid
$ ./getegid
0
The expected value in the last run is 43 (or whatever the gid of utmp is on
your system).
Thanks,
Marcus

Fact is, that the user id is always used.
The following change in libdiskfs should fix it:

* file-exec.c: Initialize GID with st_gid rather than st_uid.
