[CLUE-Tech] Permissions?

[Angelo Bertolli]

Follow-up... thanks, I looked into it with a friend.

After all, it does make sense that if you have write permission to a 
directory you should be able to remove that entry from the directory 
file.  And then UNIX automatically removes from the inode table any file 
which has no more hard links to it.  So that makes sense but...

For security purposes, shouldn't the sticky bit be default ON for 
directories?
