HOW TO FIX THE 'READ ONLY FILE SYSTEM' PROBLEM WHEN RC.CONF IS CORRUPTED ON FREEBSD
- If somehow you have messed up
rc.conf, you
likely are now seeing an error message like:
Read only file system
This error is likely due to some typographical error
in rc.conf. Perhaps it
is a quote mark on the end of a line that is missing,
or some other 'fat finger' mistake.
In any case, when you reboot you aren't able to write
to the hard drive, and get the
Read only file system error
message.
- In order to temporarily write to the hard drive so you
can edit
rc.conf, do the
following:
mount -u
mount -a -t ufs
swapon -a
/usr/local/bin/pico /etc/rc.conf
- After you have exited out of Pico, reboot
(
shutdown -r now) and
if you've fixed the error in rc.conf
the computer will boot normally.
- Note that this assumes you have Pico installed.
If you don't, you can still recover but you have to deal
with
vi. This text editor,
vi, is an extremely anti-intuitive
piece of software. Before you go any further, you
are strongly urged to print out a cheat sheet so that
you are familiar with vi's bizzare commands:

- If you are using vi, then the commands would be the same
as above except for the 'Pico' line. Use the following
instead:
/usr/bin/vi /etc/rc.conf
