Date: 2015jun20 OS: FreeBSD Q. When I login in Single User Mode I can not change things. I am told the filesystems are mounted as read-only. How can I fix this? A. Remount the filesystem. To remount the root filesystem:

mount -u -o rw /

The man page says: The -u flag indicates that the status of an already mounted file system should be changed. -o rw just requests the read-write option. If you get an error about fsck needing to be run, well run it:

fsck

Then try to mount again.
