Some days ago a lvm2 user added this to the wiki: https://wiki.gentoo.org/wiki/Systemd#Using_LVM2_and_Initramfs If you're using LVM you should also make sure that LVM is configured to start the lvmetad daemon because otherwise it might be unable to mount LVM filesystems during boot. If lvmetad is not started /dev/disk/by-uuid might not be populated with LVM partitions and systemd will be unable to mount them. You can enable lvmetad by doing the following modification: File/etc/lvm/lvm.conf # Set use_lvmetad to '1' for systemd use_lvmetad = 1 Since a systemd USE flag was now added due bug 493936, maybe this config could be changed depending on that USE flag Thanks
