Bug 176547

Description of problem:

After applying the udev update version 078-2, I noticed the following error in
/var/log/messages

Dec 25 11:48:35 server1 udevinfo[1874]: udev_db_get_all_entries: unable to open
udev_db '/dev/.udev/db': No such file or dir
ectory

This restricted to have most of the dynamically created devices in the /dev
directory.

I had to investigate this problem when I could not log into this system running
FC5 test1 via ssh, after applying the udev & kernel update. The error mesages I
could locate then upon ssh login failure under /var/log/secure were as below:

sshd (pid): Accepted public key for root from 192.168.0.3
sshd (pid): pam_unix(sshd:session): session opened for user root by (uid=0)
sshd (pid): error: openpty: no such file or directory
sshd (pid): session_pty_req: session 0 alloc failed

I carefully checked even /dev/pts was mounted and I tried to remount it, but
that did not helped. As discussed on Fedora-devel list, an update to initscripts
was also given a try but that did not helped either, finally a fall back to
udev-75-4 solved the problem and no related log message of udev as subjected
above was seen. 

Seems a new feature of a implimenting a DB file could not locate the expected
file, hence file seems missing for the new version 078-2.
