So I'm writing an custom init script and I want to mount / as rw. In /etc/init.d/rcS when I use
mount -t ext4 -o remount /dev/sda / it does remount as rw but when I do
mount -a (or I even tried
mount -a -o remount) with fstab:
/dev/sda / ext4 defaults 1 1
it doesn't and / is mounted as ro. What is going on here?
