.SH DESCRIPTION
|
|
|
|
|
The ezjail framework provides a simple way to create many virtual FreeBSD
|
|
|
|
|
servers by using FreeBSD's jail system. It requires little administration
|
|
|
|
|
effort and aims for minimum system resource usage.

.SH OVERVIEW
|
|
|
|
|
One
|
|
|
|
|
.I base jail
|
|
|
|
|
is filled with most userland binaries and libraries and then mounted
|
2005-09-20 21:52:57 +00:00
|
|
|
read only into a number of stripped down jails via
|
2005-09-05 22:59:53 +00:00
|
|
|
.B mount_nullfs(8)
|
2005-09-20 21:52:57 +00:00
|
|
|
- thus saving lots of inodes and memory resources.

.SH INVOCATION
|
|
|
|
|
The ezjail script
|
|
|
|
|
.B EZJAIL_PREFIX/etc/rc.d/ezjail.sh
|
|
|
|
|
takes parameters
|
|
|
|
|
.I start, restart
|
|
|
|
|
and
|
|
|
|
|
.I stop.
|
|
|
|
|
It may be passed an additional list of jails. If no jail name is
|
|
|
|
|
specified (usually when the script is being called by rc.local at boot
|
|
|
|
|
and shutdown time), all jails in ezjails config directory are being
|
|
|
|
|
started/stopped.
|
|
|
|
|
|
|
|
|
|
The script then examines its config directory, sets config variables
|
|
|
|
|
for each jail in the jail_list before passing its command on to the
|
2005-09-20 21:52:57 +00:00
|
|
|
.B /etc/rc.d/jail
|
|
|
|
|
script.
