uucico can't create a lockfile in /var/lock (permission denied)

[Michael Bienia]

Since the change of the permissions for /var/lock in initscripts 2.86.ds1-6ubuntu7 uucico can't create a lockfile in /var/lock anymore.

uucico lilly - (2006-02-05 20:10:02.95 5728) ERROR: creat (/var/lock/TMP0000001660): Permission denied

uucico is suid uucp and sgid dialout. A lock file from uucico has as uid/gid and permissions:
-rw-r--r-- 1 uucp dialout 11 2006-02-06 13:50 LCK..lilly

Same for me.
The reason is, the directory is mounted with the permission 0755. Should'nt it be 1777? I have temporarly solved it by changing the corresponding line in mountvirtfs.

[Michael Bienia (geser)]

I did the same (changing the mode to 1777).

I checked the permissions of /var/lock on a Debian system (I had no other Ubuntu system to check) and there the permissions are 1777.
According to the changelog the permissions were changed for Ubuntu because of security concerns.

The change of the /var/lock permissions was probably a mistake; reverted to 1777.
