[MacTUG] login hook "stuff" as mentioned at the meeting

[Ian Turner]

we started with the NHR package, several years ago (and several versions 
ago), and received permission from the original author to adapt it for 
our use

http://jochsner.dyndns.org/scripts/NHR.html

In particular, we didn't "upgrade", to the new Leopard Package, but 
retrofitted some of the Unix level changes to our original scripts.

Then of course, with Leopard, we actually "removed" the "Home 
Redirector" part of the code, because we are using the "built in to Open 
Directory/WorkGroup Manager" functionality.



***** NOTE: there was some "old code" that I was remembering for su'ing 
as the local user, but has not been in use for a long time; now it just 
runs as root.
- a sample fragment:
-------snip---------
#This section will delete the Fonts, Microsoft User Data, AppleWorks 
User Data, and Microsoft Preferences folders from the current user's 
network home location

su $1 -cf /bin/sh <<EOF
rm -rf $home_loc/Library/Caches
rm -rf $home_loc/Library/Fonts
rm -rf $home_loc/Documents/Microsoft\ User\ Data
rm -rf $home_loc/Documents/AppleWorks\ User\ Data
rm -rf $home_loc/Library/Preferences/Microsoft
EOF
