17 You are getting this error from openrc, which means the initramfs
18 has already done its stuff and passed control to init on the real root
19 partition. At this point /usr is already mounted, it is the openrc
20 startup of LVM that is failing, because it is trying to write a lockfile
21 to a read-only filesystem, which would be the case even if you were not
22 using an initramfs.
23
24 The problem is that it is trying to write to /var/lock, which is on / at
25 this point, rather than /run/lock, which is on a writeable tmpfs.
