Thank you for your reply :)
The head of the code would need something like this:
$server = "nfs-server.domain.com"
$prefix = "/our/prefix"
# Arrays to iterate over, which would be a little longer than this
$proddirs = [ "201201", "201202", "201203" ]
$testdirs = [ "201201", "201202", "201203" ]
$devdirs = [ "201201", "201202", "201203" ]
$nfsopts = "tcp,hard,intr,rw,bg"
By "iterate" I meant to work through a specific array, such as above.
Reading through the Mount part of the docs, I don't believe that "absent"
will remove the actual directory point, it says:
"Set it to absent to unmount (if necessary) and remove the filesystem from
the fstab"
So I would handle that by running another iteration over an array for each
section that would have a routine to make sure it's "absent" and then also
rmdir the entry in the filesystem.
I'm not understanding where the below is iterating or over where... as
$name would need to be defined somehow.
Thanks!
