Greetings,

Summary: If the APM_EMULATION kernel option is enabled (and built-in),
fsck during boot may be skipped all the time.

Longer story: One day I noticed some virtual machines have huge "mount
count" values, and "next check after" at a date far in the past. (I have
enable_periodic_fsck set.) After some research I learned I had (by
accident) enabled the APM_EMULATION kernel option. So /proc/apm exists
but has more or less static content[1]. The important part is is_on_batt
in e2fsck/unix.c which reads the AC status as 0xff ("unknown"), and
effectively treats this as "on battery".

So may I ask you to re-visit that check in that regard? I'll disable
that option anyway, other people still might get into trouble because
of that.

All the best,
    Christoph
