Wikipedia and versioning

[Sdävtaker]

Hello
I was looking for some info about "how i explain my boss i need a SVN
to dont kill myself" and found this doc
:http://en.wikipedia.org/wiki/Revision_control
At section 7 they list:
# Versioning file system
    * Files-11 filesystem for OpenVMS supports file versioning
    * Fossil filesystem for Plan 9 supports intervaled snapshots
    * ZFS filesystem for OpenSolaris supports intervaled snapshots

Should we add HammerFS here? and a link to the pages in the dragonflybsd manual?
If you want it to be added, i can do it.
