This patch should not be applied, but I see it has been applied anyway
meanwhile, So we might have to solve this issue differently.
This is actually the cause of my console not coming up. It was coming up after
15 minutes
systemd-analyse blame said systemd-tmpfiles-setup-dev.service is taking 14 mins
to come up.
I then traced through it and the problem is evident that its trying to write
journal when creating /dev entries but we have delayed the journald starting
point and caused a use-before-define situation.
I deleted /var/volatile symlinks and let /var/log be proper directory and same
for /var/tmp. All worked fine, without this patch. We should probably stop
doing /var/volatile thing anyway its not in FHS standard either, for ro-rfs do
something else ( may be copy-binds into /tmp/) and for general case just leave
it alone.
