HAMMER2 snapshots and other help

Hi guys,

I am trying to get a dragonfly server going and have chosen HAMMER2 as
the FS. I am having a hard time getting going because I cannot find a
quick start tutorial. I am currently using ZFS with FreeBSD and I
could figure out the basic operations after some time, but with
dragonfly I cannot find examples.

I am currently struggling to figure out how to make and use snapshots.
I saw the command:

hammer2 snapshot /home/mydir /snaps/mydir.s01

which I thought would create a snapshot under /snaps/mydir.01 but
that's not what happens...

how does one view the contents of a snapshot? How can I list them?

hammer2 pfs-info shows them but I thought I can see their content and
even edit it.

I am trying to replicate my FreeBSD server with jails (ezjail) and ZFS
on DragonFly and HAMMER2 anyone have a handy short cheat sheet?

Thanks in advance.
