With the ancient LVM1 issue, my main problem was indeed that mkinitrd did
not reserve enough space for the initrd. The LVM issue I posted to the LVM
list was that LVM userland (vg_cfgbackup.c) did not check for errors while
writing to the fs. The (ignored) patch added some error checking.
But that's ancient, I think we can forget about that.
The current issue (please see the first link) is about the need to add
a "sleep 5" between
lvm vgmknodes
and
mount -o defaults --ro -t ext3 /dev/root /sysroot
.
Otherwise, mounting fails. (Actually, I added "sleep 5" after every lvm
command in the init script and did not narrow it down any more, since this
was a production system, each boot took ages, and I had to get the system up
as soon as possible.)
To me it seemed some kind of problem with the lvm utilities, not with the
initscripts. At least, the correct solution cannot be adding "sleep 5" here
and there in the initscripts...

It is still open.
Sadly, the only two systems this currently happens are production boxes and
I cannot boot them at will for debugging. It is, however, 100% reproducible
and I can try reasonable suggestions when I boot them the next time. Sorry
about this.

No, since I wasn't sure the problem actually was in the initscript. Perhaps
it does do something wrong, but the "sleep 5" workaround is pretty
suspicious.
Thanks for the reply.
