Nils,
I understand that FAT doesn't recognize linux perms. I guess I imagined
that when I copied a file from a FAT filesystem (or any filesystem for
that matter) to a filesystem with ACL's enabled that it would inherit
the ACL's that I set the folder to be.
Also, I'm not trying to archive anything this way, some folks find it
useful to put files onto a jump drive to edit while they are away from
work and when they come back to work and put the files onto the file
server, the files don't inherit the ACLs set on the directories :(
I admit that I'm still green and don't quite grasp all of this.
Maybe a better question would be how do I get files that I copy into a
folder to inherit the folders permissions and set the group owner to the
group owner of the folder.
Thank you for your response!
