UFS

Migrate FreeBSD root on UFS to ZFS

At ${DAYJOB} I’m using a FreeBSD workstation for quite a while. Everything goes smoothly except for the filesystem. When I first installed it, I chose UFS because FreeBSD installer said that root-on-ZFS was “experimental”. I later learned that nobody uses UFS anymore and that root-on-ZFS is perfectly stable. Thing is, I chose UFS and I deeply regret it. Not because of ZFS‘s features that absolutely do not matter for me on the desktop, but because FreeBSD implementation of UFS is terribly, terribly slow when it comes to manipulate big files.
