Why is root filesystem mounted read only while bootup on RHEL7 cloud images when bind mount for /tmp is added to fstab ?
Issue
- ON RHEL7 cloud images or RHEL 7 AMI instances , if a /tmp bind mounted is added , the root filesystem is mounted as read-only .
- Root filesystem is mounted as read-only with following bind mount for /tmp in fstab & startup script .
/etc/fstab:
/tmp /tmp none bind,noexec,nosuid,nodev 0 0
/etc/rc.d/init.d/local:
mount -o remount /tmp
# ln -s /etc/rc.d/init.d/local /etc/rc3.d/S99local
Environment
