Something happened recently in an update that’s rendered my system unbootable -
am currently booted into an old (4.0.4) kernel after messing around with the
boot parameters (specifically setting ROOT=/dev/sda7 and removing rhgb and
other things).
Does anyone have any suggestions as to what it might be?
/etc/fstab is
