|
| Viola! I was in a new virtual Linux box, logged in as root, setting at
| the bash prompt, in the new virtual root.
|
| pretty cool, but I still don't know enough for it to be useful.

I don't know about chroot'ing an app. I think jails are for users, not
applications. If you chroot'd yourself into the jail, then launched
firefox, it wouldn't launch unless you had everything you needed for
your X to work as well...Which would be so much stuff you'd not have
much benefit from it.
The only thing I know to use chroots and jails for are for the
users...IOW, when you chroot your apache, you're jailing the apache
user, not the files or programs inside.
IOW, you can do it...Technically, but the benefit would be minimal.
I use jails for that whole backup scheme we were discussing last week,
and I also use it for a few daemons such as apache and the ftp server.
