Hello Brent,
The deal is, that you are accessing/deleting the files from LINUX,
and the users are accessingthem thru samba.  Depending on how you have 
certain locking parameters defined in your smb.conf file (oplocks, locking,
strict locking), the pc useage of the files on this disk does not 'bleed'
to the LINUX level, so linux doesn't know (or care) that someone is using
esp when a client is using a file with an oplock, that typically ONLY samba
keeping track of.

As long as the files that you are updating are executables, and you don't
to worry about data corruption, this is probably just fine. You MIGHT run
an issue if you are in the middle of an update while people are using these
in that they might get mixed revs of the main programs and/or some dlls, but
up to you.

Hope this helps,

I have been messing with this and it seems to work, but I would like to hear
if it does or not from the people that have created it.

On a WindowsNT machine I have three directories shared out READONLY.  These
three directories are mapped to users machines and then they run programs
out of them.  There are ALWAYS people using files in here.  At times I have
to update the programs in there and I need to overwrite the files that are
in there.  Now on this windowsNT machine I cannot seem to do that without
killing all of the connections and doing it because they are locked due to
people using them.

Same situation but with SAMBA on a linux machine this time.  I have tried a
few times and it seems to have no problem overwriting the copies that are on
disk while people are still using them (at one point I actually deleted all
of the files in there and it didn't complain).  Is it true that SAMBA will
allow this or have I just been lucky so far?
