[opensource] Preventing removal of symbolic link

[William Triest]

Can anyone think of a good way to prevent a user from removing a 
symbolic link in their home directory?

By default symbolic links of full permissions and there is now way to 
remove them (at least that I am aware of).  Since its the users home 
directory they can remove them.  I looked into acl's but haven't found 
an obvious way.  A solution which didn't prevent the user from removing 
them, but which just made it so a simple rm wouldn't remove them would 
be good enough.   I just don't want a simple rm to be able to remove 
them in order to avoid the number of accidental removals (and then 
support requests for me to restore them).

Thanks,
Bill
