Trouble is this is really not a problem with Bacula, but rather a config
question on your operating system. I would not do a chmod on that file.
If you're using kernel 2.6, chances are good that you might be using
devfs -- these files are not created on the filesystem like on older
versions of Linux, and are dynamically configured by devfsd. Type
`mount` or `ps -ef | grep devfs`. I don't currently have a system with
2.6 and devfs -- apparently RHEL doesn't do things that way. If this is
your problem, check the documentation for devfs.
As far as why bacula cannot perform operations on the file when it has
group write -- don't know. I never was very good with gid vs. effective
gid. I started out on IRIX, and if I recall correctly, IRIX doesn't do
things quite the same as Linux, and I've had a tenuous grasp on the
situation ever since.
The bottom line is it would probably be good for you to become more
familiar with your platform, or you're going to have problems down the
line anyway.
