[Voyage-linux] when remountro fails

[tictacbum]

Hi, I noticed filesystem was not getting checked on boot, although
mount-count set to 1
I solved it adding this line to /etc/fstab:

/dev/disk/by-uuid/970c07f8-a269-42e5-9df2-b7d8036234c6 / ext2 ro,relatime 0 1

now it makes an fsck on every boot, but has to reboot when fsck ends
the only (small) problem is that it takes a bit longer to start, apart
from the check time, it reboots after fsck
