One thing I think he's thinking about, when it comes to acl setting is
something like this:

server[/home/userx]#>chacl u:5:,g:4:,o:0: somefile
server[/home/userx]$>chmod 777 somefile
server[/home/userx]$>ls -l somefile
-rwxrwxrwx    1 userx   userx     72178 May  15 10:25 somefile


I don't quite understand here. What good is setting ACLs on files if they
don't stick? Aside from that, that's my only gripe. I need to go do some
testing with directories next. :)
