Actually I did a little testing, and contrary to comments in 
Default.sample $LOGIN is not defined, but $USER is, so test that instead.

So Default should contain something like this:
#!/bin/sh
#
if [ $USER == "library1" ] || [ $USER == "library2" ]
then
 rm -rf $HOME
 cd /
 cpio -dumi -F /home/$USER.cpio
fi
exit 0


Of course you need to create a cpio archive of the homes first as root:
find /home/library1 | cpio -o -O /home/library1.cpio
find /home/library2 | cpio -o -O /home/library2.cpio

Enjoy!
