[Bug 2035161] Re: Device busy after starting guided LVM install

Tue Sep 12 17:09:52 UTC 2023

Hi Phreed, thanks for the report.

There seem to be glitches in that area, and for whatever reason LVM is
good at triggering it.  If you repeat the install I bet it works for you
the second time.

curtin-side I suspect this is the same problem that is being worked
around in commit 412ffeb08e8b981005a8342d93816e5bc2cc63a5.
