And the answer is that you can't remount the filesystem with ro option.
You can do it with other SO, like Linux, but not with Solaris. I don't
know why, because this is a useful capabilitie. I, and many other, use
to mount /usr with ro option, and sometimes I have to remount it with rw
option to install software, but I don't want to reboot the system and I
can't umount /usr filesystem.
Summarizing, I think this will be a good enhancement to ufs filesystem
of Solaris
