Hello! In order to test the new shiny msk driver, I've installed 6.2-PREPELEASE and then upgraded it to the CURRENT as of date=2006.09.26.00.00.00 (to overcome recent libalias breakage, and also to make sure that msk.HEAD.diff will apply cleanly). I've noticed the something very new (and annoying) after the upgrade: all filesystems listed in /etc/fstab with "ro" are still mounted as R/W. Here is my /etc/fstab: # Device Mountpoint FStype Options Dump Pass# /dev/ad0s3b none swap sw 0 0 /dev/ad0s4a / ufs rw,sync 0 1 /dev/ad0s4e /usr ufs rw 0 2 /dev/ad0s3a /mnt3 ufs ro 0 0 /dev/ad0s3d /mnt3/usr ufs ro 0 0 and here is 'mount' output: $ mount /dev/ad0s4a on / (ufs, local, synchronous) devfs on /dev (devfs, local) /dev/ad0s4e on /usr (ufs, local, soft-updates) /dev/ad0s3a on /mnt3 (ufs, local) /dev/ad0s3d on /mnt3/usr (ufs, local, soft-updates) I also can write under /mnt3, so 'mount' correctly shows FS status. mount _does_ obey 'mount -ur /mnt3', it just ignores "ro" in /etc/fstab. Booting into the single-user mode and making 'mount -a' has the same effect. Is this breakage well-known, or something new?
