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.
I copied the /dev tree in /var/run/dev, which is detared from /var.tgz
during boot. Then I run :
mount_mfs -i 256 -s 592 -P /var/run/dev swap /dev
And it is ok.
df -hi /dev gives :
Filesystem Size Used Avail Capacity iused ifree %iused
mfs:4304 23.0K 4.0K 18.0K 18% 232 1686 12% /dev
good...
Thanks.
