“Problems with the SVN->CVS exporter” has resolved!
The next snapshot, BETA3, has been delayed as a result of problems with the SVN->CVS exporter when creating the stable/8 branch. This problem has now resolved by PeterWemm and SimonNielsen, and the release engineering team has begun approving patches with the goal of shipping BETA3 around 17 August.

FreeBSD 支持层级架构的Jail系统
Add hierarchical jails. A jail may further virtualize its environment by creating a child jail, which is visible to that jail and to any parent jails. Child jails may be restricted more than their parents, but never less. Jail names reflect this hierarchy, being MIB-style dot-separated strings.

X.org 7.4 merged in ports
http://www.freshports.org/x11/xorg/
– Update X.org ports to 7.4+ (few ports are more recent than the katamari).
- Bump PORTREVISION for all ports depending on libglut since the shlib version number went from 4 to 3.
- Bump PORTREVISION for all ports depending on libXaw as libXaw.so.8 isn’t installed anymore.
- Couple of ports fixes (mostly missing xorg components added to USE_XORG).
“18 points” on why one writer thinks FreeBSD is better than Linux
1. BSD license allows users/companies to modify a program’s source code and not to release changes to the public
2. BSD has the so-called “core system” (without packages)
3. On BSD systems, all add-on packages are strictly installed into the /usr/local directory
4. BSD systems use the system of “ports”, which are fingerprints of applications in the /usr/ports directory
5. BSD systems have also their stable version
6. Of course, the kernel is absolutely different
7. BSD has FFS file system
8. BSD systems divide their partitions internally
9. Unless you make a good kernel hack, BSD systems can only be installed into the primary partition
10. System configuration is manual for most of the time, but various clones like PC-BSD break this convention
11. All BSD systems have a Linux emulation support
12. BSD systems have less support from driver vendors, thus they lag behind in this view
13. BSD systems do not use the Unix System V
14. BSD kernels can be set to several security levels
15. BSD’s have everything under one ROOF
16. Generally, BSD systems boot and reboot faster than Linux
17. In comparison to BSD, most Linux distributions are overbloated
18. If you compile programs from ports, you will not stumble into compilation errors

[ZT] Best practices for using gjournal with gmirror
FROM: http://unix.derkeiler.com/Mailing-Lists/FreeBSD/hackers/2007-01/msg00220.html
—
[Q:] When using gjournal and for a gmirror volume, does the journal need to be mirrored as well to maintain redundancy? If so, when storing the journal on the same physical disks as the mirror, is it better to mirror at the slice level (journal and fs on different partitions in the same mirror) or at the partition level (journal and fs each have their own mirror) or does it matter?
[A:] The problem with mirroring each partition/slice separately is that when you have a crash, on boot, gmirror will start to rebuild all partitions at once, which may be problematic. On the other hand, when you mirror each partition/slice separately, and some partitions weren’t modified in last few seconds before the crash, gmirror will not resync them on boot, so not entire disk will be synchronized.
注:Gmirror如果对整个硬盘作镜像,系统崩溃重启后,gmirror将有较大可能需要自动重建所有分区(如果是1T HD,会是个大问题)。
如果对每个分区单独做镜像,如果某些个镜像分区在崩溃前几秒钟没有发生修改/写操作的话,镜像状态不会降级损坏,gmirror 就不需要在重启后重建这个分区,(如果将需要频繁写入的分区划为小于20G的独立分区做镜像,就可以一定程度上绕开以上的问题)。
When you run gjournal on top of gmirror/graid3 there is no need for resync after a crash, so bascially all cons against mirroring the whole disks and against mirroring partitions are no longer true. Both configurations will work the same. In that case I’d suggest mirroring the whole disks, because when one of your disks dies, you may just replace it and be down with it. If you mirror partitions separately, you first have to create partitions and insert each of them into their mirrors, which is more complex than simple ‘gmirror insert foo newdisk’.
注: 如果在Gmirror上启用gjournal, 就可以很大程度上避免在崩溃重启后重新同步(?) 这种情况下,推荐对整个硬盘做mirror。

[Q:] does a gjournal volume need to be fsck’ed after a crash? If not, will it just work (e.g. fsck -p sees that the filesystem is clean) or does it need to be disabled somehow?
[A:] Gjournaled file system has to be fscked, but only to handle orphaned files. Such fsck on multiterabyte provider takes seconds, not hours.
注:gjournal 系统同样需要fsck, 但是非常迅速。

BSD Hammer streaming 的一些信息
看样子有点像 Linux 下的 DRBD
two disks can be synchronized over a network link of any speed or reliability – it can be restarted and immediately begin where it left off, and the amount of bandwidth used can be controlled…
