Bug Description

I am running a system with a separate /var partition - this causes errors due to various services being started before the /var partition is mounted. As an attempt to fix this, I have tried adding the x-initrd.mount option to the entry in /etc/fstab for the /var partition, according to http://www.freedesktop.org/software/systemd/man/systemd.special.html this should add the partition to the sysroot-usr.mount target.

Example fstab entry

UUID={*irrelevant to bug report*} /var ext4 defaults,x-initrd.mount 0 2

What actually happens is that this causes the partition not to be mounted at all after boot. Using sudo mount -a does nevertheless successfully mount the partition.

Reproducible: always
