People concentrating on interoperability uses of filesystems are out of their minds to be writing them in-kernel, when they could be running them from userland as userland nfs servers, accessing the raw disks. All we need is to make this a default part of the system, add a libuserfs to provide an abstraction layer, and tada. Let me know when there's a JFS4NFS and I'll give a damn, cause then I can use it everywhere I'd need to. FWIW, background fsck and softdep and ufs2 will give you all of the good stuff you *see* from using a journaled fs, without the corruption of a whole disk, like my girlfriend's laptop went through, running with Linnex XFS. juli. -- Juli Mallett | FreeBSD: The Power To Serve Will break world for fulltime employment. | finger jmallett@FreeBSD.org http://people.FreeBSD.org/~jmallett/ | Support my FreeBSD hacking!
