That was the original intent of this thread from what I can see. It's been discussed previously on the FreeBSD lists. In a previous post to DragonFly lists I suggested such features might need be developed further before potentially finding interest in the wider BSD arena. *BSD should implement and refine (in a BSD style) these types of advanced features for their merits, not only because they exist elsewhere. So basically, for the FreeBSD project, this could imply holding off and/or reworking the facility until it is made less experimental, though this assumes some implicit set of flaws in the DragonFly implementation which with time may be disproven. Some technical caveats have been enunciated previously on list. > Siddharth Aggarwal wrote: > > >Hi all, > > > >I am responding to a post back in Oct 2003 when the checkpointing feature > >was announced for DragonFly.
