[TriLUG] Change GID

Right, sorry.  I can't change the GID on the Samba server for a couple
of reasons.  In fstab the mount command sets the uid and gid of the
files on the shared drive.  I also force user and group in the smb.conf
file of the server.

My mount works like so:

/home/jjtuttle/Documents/work/ndiipp_project/ndiipp_scripts smbfs
0 0

On the server the gid of the group who must own all the scripts is 10.
However, on my local machine, 10 is the gid of uucp.  Since I can't
change the gid on the server, I was hoping to change the gid of uucp on
my local machine.  I understand how to change gid with groupmod, but am
worried that doing so may wreck something.  I mean, if I create a local
group 'staff' with gid 10, and change the gid of uucp to 20, will the
files currently with gid 10 be screwed up?

Man, sometimes I just want to stuff to work.  Maybe a Windows Vista
license would.... bwah hahahahah!  Ok, back to sanity.

Thanks for helping,
