OnTap WAFL’s .snapshot feature is such easy to use since years while on FreeBSD UFS2 the
unprivileged users were not able to as easily use snapshots for retrieving old stages of their files.
To solve this I’ve implemented a little snapshot management environment for FreeBSD around mount(8), mdconfig(8), amd(8) and cron(8) which provides a
similar environment than what people are used to from WAFL.
A summary article and proof of concept implementation is available.
