According to Greg Lehey: > Right, most System Vs I know with this method call it /stand. But > that name is taken :-) On Tandem, the boot file system is (wait for > it) bfs.

On SVR4 (at least some of the older 4.0 ones) used bfs as the filesystem used for /stand. It is much simplier than UFS (contiguous allocation and all that) and fits in the boot blocks. > Well, you *could* tell me which parts are cool and why.

The LVM module from AIX is even better because you don't need to unmount the filesystem before (HP does it with an extra package called OnlineJFS). You have Physical Volumes, grouped into Volume Groups, each Volume Group is divided into Logical Volumes and a LV can contain a filesystem. A given filesystem is extendable within a LV and you can enlarge a LV. Probably near what Veritas' stuff does. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 4.0-CURRENT #70: Sat Feb 27 09:43:08 CET 1999 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
