The problem at boot might be related to the fact /boot is located on a
lvm partition, otherwise I can't think about anything.

OK, I'll check the installation problem on a container later, but if I
install sysv-rc or current openrc package, then the installation of lvm2
fails because the dependencies aren't enabled. Enabling those manually
does solve this, but openrc 0.20.4-1 does not have this issue. I did run
rm -r /etc/rc?.d; insserv -d /etc/init.d before installation of lvm2, so
it shouldn't be caused by some strange state of /etc/rc?.d.

Yes, it is related to openrc, as openrc seems only affected because of
the use of init-system-helpers to provide update-rc.d, which does not
seem to use openrc to determine the dependencies. Nevertheless it should
probably be reported to init-system-helpers.
