Looking at the CVS logs for sbin/tunefs/tunefs.c shows ---------------------------- revision 1.7 date: 1999/01/20 01:22:39; author: luoqi; state: Exp; lines: +47 -4 branches: 1.7.2; Allow tuning of read-only mounted file system. --------- which is (IIUC) before 3.1-R. But there is some other magic to do with whether the root partition is RO or RW when booting that is (i think) later. Note that 'shutdown' is not the same as 'boot -s': In the latter case, the root partition is mounted read-only and has never been mounted writable (since the last boot). In the former case, the root partition was mounted writable in multiuser mode and there is no way to go back to read-only, so the root partition is still writable (and hence not tunefs-able) in single-user mode.
