FreeBSD Today Jeff Roberson committed his patches to FreeBSD 9 for adding journaling to UFS. No more background fsck after unclean shutdowns! This is a major landmark in the history of UFS, with 11000 new lines of code (and about 2000 removed). Much of the work was done in collaboration with Kirk McKusick, the original author of FFS and Softupdates, under sponsorship form Yahoo!, Juniper and iXsystems. Jeff's blog contains quite a lot of technical information of his work. There's also information on the FreeBSD mailing lists.

RE: Why isnt Hammer in FreeBSD??

Member since:

Maybe because they are strongly reluctant to import the coding marvel of the very same guy they had kicked out?

Maybe because the code doesn't have a "FreeBSD feel to it" .. like in Murenin's port of the OpenBSD sensors framework to FreeBSD (GSoC2007/cnst-sensors)?

Maybe because they decided that with all the money, devel time and debugging effort they spent porting ZFS, ZFS should be the FS you should use regardless of wether it is or it is not a better FS than Hammer?

Maybe because of the same reasons why the keep Sendmail in base instead of moving it to ports and import DMA or OpenSMTPD to base (which are _nothing_ but historical reasons)?

Go ask FreeBSD satus quo ... they probably have a rock solid and scientific explanations about it like "Because it has been there from the beginning" or something lines along that way ..

Anyways, my congrats and sincere thanks to Jeff for his work. It will be highly aprecciated in my ZFS free world ;)
