Comment 5 for bug 1000770

I've hit this bug even tough I've applied the fix discussed in comment #6 of bug #964957.

Specifically I've built partman-auto-lvm_42ubuntu2+dannf2_all.udeb from the 38th revision of https://code.launchpad.net/~dannf/partman-auto-lvm/precise-fixes, and installed that udeb using an early command. I've also confimed that /bin/perform_recipe_by_lvm contains the update-dev --settle line.

It happened for me just as in Sgifford reported, but with swap partition instead of root. I'm preseeding the partitioning. The workaround he suggested (running vgscan --mknodes) works for me too.
