Typically, when you boot the kernel, you do so passing a read-only (ro) kernel option, like this:
kernel /boot/vmlinuz-2.6.24-23-generic root=UUID=xyz ro quiet splash
If you have to, in an emergency, how bad is it if you don't pass the ro option, like this:
kernel /boot/vmlinuz-2.6.24-23-generic root=UUID=xyz quiet splash
kernel /boot/vmlinuz-2.6.24-23-generic root=UUID=xyz ro quiet splash
If you have to, in an emergency, how bad is it if you don't pass the ro option, like this:
kernel /boot/vmlinuz-2.6.24-23-generic root=UUID=xyz quiet splash
