If you read Margo's thesis, the huge memory consumption is the big problem of Sprite and LFS is supposed to need less memory. One of its biggest problem apart from being incompatible with the unified buffer cache/VM is that many features were never implemented (like the rollback fsck). The thesis is very enlightning on FS and their flaws BTW. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #54: Mon Jan 26 20:29:17 CET 1998
