yar 2008-02-14 17:04:31 UTC FreeBSD src repository Modified files: sys/kern vfs_mount.c Log: In the new order of things dictated by nmount(2), a read-only mount is to be requested via a "ro" option. At the same time, MNT_RDONLY is gradually becoming an indicator of the current state of the FS instead of a command flag. Today passing MNT_RDONLY alone to the kernel's mount machinery will lead to various glitches. (See the PRs for examples.) Therefore mount the root FS with a "ro" option instead of the MNT_RDONLY flag. (Note that MNT_RDONLY still is added to the mount flags internally, by vfs_donmount(), if "ro" was specified.) To be able to pass "ro" cleanly to kernel_vmount(), teach the latter function to accept options with NULL values. Also correct the comment explaining how mount_arg() handles length of -1.
