Well, hm, OK, that is interesting.  But how does it apply?  Entering:
chattr -i /nfcs/Testit
has no effect on the file's executability.

Anyway, it did get me thinking about the fact that the test directory is in
its own partition, so I typed mount and found it to be mounted:
/dev/hda8 on /nfcs type ext2 (rw,noexec,nosuid,nodev)

What?!?  No execution?  So I checked /etc/fstab and it is listed:
/dev/hda8   /nfcs   auto     defaults,user     0 1

So where does this (rw,noexec,nosuid,nodev) come from?  All of my partitions
are mounted "defaults" and the others have only (rw).

More importantly, how can I change it?  If I unmount it and remount using:
mount /dev/hda8 /nfcs
it is mounted (rw) and I can execute the script.
