Hello, A few experiments on 1.5 nullfs showed that it ignores the read-only flag:
/mnt: mkdir 1 2 /mnt: mount_null -o ro /mnt/1 /mnt/2 /mnt: mount .. /mnt/1 on /mnt/2 (null, local, read-only) /mnt: cd /mnt/1 /mnt/1: echo > k /mnt/1: cd /mnt/2 /mnt/2: rm k /mnt/2: ls /mnt/2: cd /mnt/1 /mnt/1: ls -ltr total 0 /mnt/1: I could delete a file on a read-only filesystem. Oops. Regards, David.
