Title: Writing To The Read-only Filesystem?
Post by: Ventmore on April 27, 2006, 05:13:16 pm

I would like to modify the /root/etc/rc.d/rc.sysinit file (to get home on sd), but it says that it is a read-only filesystem.  I have seen a couple of commands in different threads to remount / as writeable, but it always says permission denied...even though I am root.

Any ideas......I have a 5500 with Sharp ROM 3.13.

Cheers

Bad news...

You have / with cramfs. You can't write in a cramfs....
Your last chance is get a unionfs of / and another writeble place.
