Its a wonderfull improvement and my FS of choice > when installing on new machines (especially zfs boot) I think that you're touching on two entirely separate points here... What it takes to upgrade ZFS in -STABLE and what it takes to bring ZFS modules in to FreeBSD. I sincerely hope that ZFSv13 is planned for -STABLE. Last we left this issue, testing and a few kernel improvements were in the way. None of the kernel improvements were going to change the API, so the project was doable in -STABLE. That said, time marches on, 8.0-RELEASE draws ever nearer. When we were still several years out on 8.0 and ZFS was causing me more problems, I was much more keen to push for the port. I would still welcome it with open arms, but I'm not convinced that anyone is going to push it forward. The issue of encryption (along with many other issues) is tied to the ability of FreeBSD to compile and use ZFS modules. Just like netgraph modules extend the function of netgraph.ko and geom modules extend the base geom function, ZFS is designed (in Solaris, at least) to take modules. ZFS encryption is a module. I'm not clear on compression --- it would make sense that it is a module, but it seemingly got copied into FreeBSD as a core feature (and it may also be so in solaris). Anyways... is there any plans to allow for ZFS modules in FreeBSD? _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
