Jail & nullfs how many

[Albert Shih]

Hi all

I'm starting using jail and I'm using now nullfs (I don't really want use
something like ezjail or other plug&play script, I want understand what I'm
doing before using this tools).

I'm making a /jail/REFERENCE using classic make world etc...
and mounting using nullfs 

/jail/REFERENCE/bin --> /jail/my_jail_ip/bin
/jail/REFERENCE/lib --> /jail/my_jail_ip/lib
/jail/REFERENCE/libexec --> /jail/my_jail_ip/libexec
/jail/REFERENCE/sbin --> /jail/my_jail_ip/sbin
/jail/REFERENCE/usr --> /jail/my_jail_ip/usr
/jail/REFERENCE/var --> /jail/my_jail_ip/var

by using this I'm hopping have just one /jail/REFERENCE to update when I
need to rebuild world.

Well two questions : 

	it's the right thing to do ?

	How many nullfs I can mount ? Because there are 6 by jail, if 
	i'm going to use this many I have 10-20 jail. Can I mounting ~120
	nullfs without problems ?

Regards
