[kwlug-disc] Sharing ZFS joy

[John Sellens]

It might be even easier than that.

I think the default is that snapshots are visible in .zfs/snapshot
in the root of the filesystem.  So, if you have a zfs filesystem
    mypool/home
mounted on /home (or /mypool/home), then you may be able to browse
snapshots in
    /home/.zfs/snapshot
without doing a clone.

Normally the .zfs directory doesn't show up in ls (or ls -a)
so you have to know to look for it.

Or at least that's my experience.

Cheers

John
