Hi all,

What is the purpose of the following line in /etc/profile.d/ssh-key.sh ?

[ $SHLVL -gt 1 ] && EXIT=exit || EXIT=return

It prevents me from opening any sub-shell like screen (or ctrl-o in
midnight-commander).
Is it really necessary to check the shell level?

When I comment out the following "$EXIT $?" statements, sub-shells work
fine, and I haven't seen any unwanted side effects.

This is on Rocks 5.4.3
