The real fix is to make "struct buf" more object oriented, so that instead of bwrite(bp) one does bp->b_op[BOP_BWRITE](bp) (possibly through a suitable #define.) Once this is in place, the UFS layer doesn't have to operate on a disk and the following things should be within our grasp: Mounting of filesystems in plain files (rather than using vn) A real VMFS or TMPFS which uses UFS as naming for anonymous VM objects. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
