bsdinstall/auto logic falls down through the partition hard drive logic 
with no way to bypass it. It will look for free space on the H.D. you 
booted from and issue message about no free space, ask you if you want 
to try another drive and then use the booted drive as target to redo the 
partitioning again thus scratching your running system. In the normal 
sense there is no way bsdinstall can be used to create jails. A jail 
does not occupies a whole H.D nor do you boot a jail as a standalone 
host. The qjail port is there for the purpose of creating and 
administration of jails.

Its not a question of how much space bsdinstall occupies on the H.D. 
after the original install. Its that some poor soul may try to use it 
and trash there newly installed running system by accident. And if there 
were multiple os's on that H.D. there all gone in a heart beat. We have 
to protect the poor user from them selfs doing stupid things.

As I understand it bsdinstall is a replacement for sysinstall. 
Sysinstall tried to be everything to everybody and turned into a can of 
worms. There is nothing wrong about limiting bsdinstall to a roll of 
"original installs" only. KISS

These 2 statements should be added at the end of bsdinstall/auto to 
complete the clean up of the install process.

rm /usr/sbin/bsdinstall
rm -rf /usr/libexec/bsdinstall

Another benefit of doing this is it will no longer be necessary to 
create man pages for bsdinstall.
