All I see is logs for pre-boot fsck, but not forced fsck via the fsck option in the recovery menu.
This is not a duplicate of Where are fsck results logged at boot time, after /forcefsck?. It mentions pre-boot fsck, not this situation where I go into recovery mode to initiate a fsck manually. I use Ubuntu GNOME 16.04, so any solutions that apply to upstart won't help either.
