The annoying bit is that `jail` has a specific meaning on FreeBSD that that is a kind of virtualization, but oddly it looks like 90% of the `chroot-jail` questions are Linux which are abusing the term.  

I am almost tempted to suggest that the [tag:jails], [tag:jail], and [tag:chroot-jail] tags be completely removed and in the cases where appropriate we add a tag like [tag:freebsd-jail].
