[luau] vsftpd-1.2.0-5

[Taylor Cody L. Contr 502 AOS/PETS]

Can someone tell me what is the easiest way to allow ftp users to upload but
not delete?  
If possible I would like to choose which users can delete.  
I think [user_config_dir] or [cmds_allowed] may get the job done.
Does the cmds_allowed apply for everyone on the server?  
Do I have to make the user_config_dir file?  If so is there a model or a
list of suggested commands I can get?

While I was researching the above questions I noticed that you can run
vsftpd as stand alone or off of another program like initd or xinetd.  The
man pages say that it runs as stand alone by default.  Can I assume this is
correct because I use the vsftpd.conf file to configure and not inetd.conf
or xinetd.conf?  When I make changes they take affect when I restart
/etc/init.d/vsftpd.  What function does /etc/rc.d/init.d/xinetd have with
vsftpd?

Any info will be appreciated.  Thanks.  -Cody
