For completeness' sake: - If even rescue.target does too much, adding 'boot.debug1' launches a minimal (initramfs) shell with nothing mounted -- or modules loaded. From there, you should be able to fsck anything with impunity. - Or be lazy like me and use "root=" combined with "boot.shell_on_fail". The initramfs will load modules for you, then hand over control to you to fsck and mount the rootfs. Hacky fun.
