Okay, so another quick workaround, now keeping the fsck enabled for the volumes:
Create a file called "/lib/systemd/upstart/systemd-fsck@.service" with: ---- # This file is part of systemd. # # systemd is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or # (at your option) any later version.

I'll provide a SRU patch for systemd in Trusty and it shall solve this issue. ** Changed in: snapd Status: In Progress => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1718966 Title: Cannot install snaps on Ubuntu 14.04 with /var on its own partition Status in snapd: Invalid Status in systemd package in Ubuntu: In Progress Status in systemd source package in Trusty: In Progress Bug description: Installing snaps is not possible on Ubuntu 14.04 when having /var on its own partition, whether its LVM or not.

I couldn't reproduce this issue by using the Ubuntu 14.04 cloud image which doesn't isolate /var on its own partition. I tried adding a secondary disk to that cloud image VM and create a dummy VG and LV, but couldn't reproduce the issue. Also could not reproduce using Ubuntu 14.04 (with LVM or not) but with only a / partition and swap.
