Hi,

I have created squashfs for our embedded board.
I excluded /mnt directory from being squashed.
I now have the rootfs "/" squashed (ro) and "/mnt" mounted on jffs2 (rw)
I tried to union these filesystems and make squashfs writeable, but it did
not work below is the command that i used

# mount -t unionfs -o dirs=/mnt=rw:/=ro none /mnt

I can create and edit files in the /mnt directory. ex: cd /mnt/etc; cat >
hello.c
but if i do the same in /etc directory it says readonly filesystem.
Can anyone please help me explain how to make rootfs "/" writeable

I appreciate your help

Regards,
Kalyan
