How to change read-only mount to read-write ?
 

Hi,

I'm running vanilla 2.6.27.35 on Embedded Pentium-M board.

The disk is divided into 2 ext3 partitions. The first is where bzImage+grub+busybox is installed. The second is for the user.

In menu.lst I set the first partition to be read only.

How can a root user change it temporarily to read-write in order to make some changes in /etc using telnet ?

Thanks,
Zvika.

Edit /etc/fstab to change "ro" to "rw" for the first partition, then change it back.

/etc/fstab is also read only
 

Hi,

I can not edit /etc/fstab. It is also read only.

Thanks,
Zvika.

Solution
 

The command:

mount -o remount rw /

converts the partition to read-write till the next reboot.

Thanks.

Root privileges are needed to edit /etc/fstab. You need edit it with root privileges, however that is done in your distro.
