I have a requirement of changing my root partition to Readonly.

After changing / to readonly in /etc/fstab, I rebooted the system.

Mount points of USB devices is /mnt.

But after above changes USB folder is not creating under /mnt/sdXX because of Read only Root partition.

Can I get any work around for this requirement please..

First thing to do is mount /mnt on tmpfs. In /etc/fstab

tmpfs   /mnt   tmpfs size=1M 0 0

That really should solve your initial problem (but I'm sure you'll have more to come!)

If this is home work ......

Just create all mount points while the system is read write. Then mount read only.

mount -o remount,rw /
mkdir /mnt
reboot

should do the trick.

  • /mnt folder exist in / partition <br/> Problem is sdb1 or sdc1 whatever mount points for usb is not creating under /mnt – mrajanna May 11 '15 at 9:11
  • Please update your question with that information, to me it sounds like /mnt doesn't exist. Though the same is true if you mean the mount points. Make it read write. then make the /mnt/whatever, reboot. Please include your fstab in your question edit. – coteyr May 11 '15 at 10:10
