Do you know that you need more than fstab(5) changes to mount / RO? > Yes, I could create a mfs partition for /dev, but I think it is too > dangerous. Works fine, you can use the -P flag to populate from another directory. Copy MAKEDEV into that directory and run it to setup; do the same at upgrade time. Also keep the existing /dev. If you use -i, you might avoid some future trouble by using 1024 or more (I didn't check why or when, but -current seems not to use anything lower). Don't worry about your CF too much, they are designed to be written to! The main benefit of mounting RO is to avoid fsck.
