New jail utility "qjail" published for public usage
This is a news announcement to inform people who have interest in jails,
that a new jail utility is available.
Has a file suitable for the pkg_add command or the port make files can be
downloaded and a "make install" run.
Qjail [ q = quick ] is a 4th generation wrapper for the basic chroot jail
system that includes security and performance enhancements. Plus a new
level of "user friendliness" enhancements dealing with deploying just a few
jails or large jail environments consisting of 100's of jails. Qjail requires no
knowledge of the jail command usage.
It uses "nullfs" for read-only system binaries, sharing one copy of
them with all the jails.
Uses "mdconfig" to create sparse image jails. Sparse image jails
provide a method to limit the total disk space a jail can consume,
while only occupying disk space of the sum size of the files in
the image jail.
Ability to assign ip address with their network device name,
so aliases are auto created on jail start and auto removed on jail stop.
Ability to create "ZONE"s of identical qjail systems, each with
their own group of jails.
Ability to designate a portion of the jail name as a group prefix so
the command being executed will apply to only those jail names
matching that prefix.
Qjail reduces the complexities of large jail deployments to the novice
level. Qjail has a fully documented manpage written for easy comprehension.
Details are given to felicitate the use of qjail's capabilities to the fullest
