Given the number of complaints I remember reading about cases where a computer which had been working fine before failed to boot under systemd, because there was a fstab entry which didn't have "nofail" set where systemd needed it to be, I find the assertion that this was the traditional behavior before systemd to be implausible. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
