====== How to remove the /ro and /rw stuff ======

Ok, I've lived with /ro and /rw for over a year and I don't like it. I don't like the fact
that I lose the log files on a crash, I don't like to hunt for the location of files, and I don't like to
hit save in my editor to find out the filesystem is mounted ro.
Maybe in a year when my flash cards give up from being
written too much I will go back, but for now, I want to eliminate this stuff. Emulate at your own risk!

Start in the top-level (root) of your distribution and run the following bash commands to move files to where they normally belong:

<code>
for f in `cd ro; find .`; do if [ -L $f ]; then rm $f; fi; done
cp -ar ro/* .
rm -rf ro rw
</code>

Now we need to fix the boot scripts:

<code>
cd etc/init.d
perl -n -i -e 'print unless /^tar/' mountall.sh
perl -n -i -e 'print unless /cp -Rp/' voyage-util
</code>

And let's take care of the remountro and remountrw scripts:

<code>
cd ../..
echo 'echo "... NO-OP: remountrw is no longer needed."' >usr/local/sbin/remountrw
echo 'echo "... NO-OP: remountro is no longer needed."' >usr/local/sbin/remountro
perl -p -i -e 's;/rw ;/tmp;' etc/fstab 
</code>

This works for me, but I can't guarantee that I didn't miss something...

Enjoy!

==== Update 2009-09-03 ====

This breaks my voyage 0.6.2 distribution. After executing the first line, my Alix doesn't find any command (e.g. "-bash: /bin/rm: No such file or directory") and can't boot either saying:

<code>
Booting 'voyage-linux-10Aug09'

root (hd0,0)
 Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz root=LABEL=ROOT_FS  console=ttyS0,38400n8

Error 15: File not found

Press any key to continue...
</code>

This is after GRUB trying to boot the kernel.

I have to reflash my SD card to see for another solution. I will try just to execute a 'remountrw' with a cron.reboot.

Note: Doesn't work with cron.reboot method.



===== Working method for Voyage 0.6.2 =====

As you can see while booting, voyage temporarily mounts the filesystem rw:

<code>
Remounting / as read-write ... 
Removing /etc/nologin ... 
Done.
Remounting / as read-only ... 
</code>

You can easily find this code in /etc/init.d/voyage-util. In line 77f. you can find:

<code>
echo -n "Remounting / as read-only ... "
#/bin/mount / -o remount,ro
/usr/local/sbin/remountro
</code>

Now you can easily comment out line 79 so that the above lines look like:

<code>
echo -n "Remounting / as read-only ... "
#/bin/mount / -o remount,ro
#/usr/local/sbin/remountro
</code>

Filesystem will be mounted rw at reboot now.
