In devmapper 2:1.02.27-2 you added udev rules to dmsetup, but not to
dmsetup-udeb. This produces some odd effects, since device names now
differ between the installer and the installed system (in Ubuntu this
resulted in LVM installations having root=/dev/dm-0 and having UUID
conversion incorrectly applied in grub as a result; the latter won't
happen in Debian but I suspect root=/dev/dm-0 is not a great idea anyway
when better /dev/mapper/ names are available).

The attached patch fixes this.

We believe that the bug you reported is fixed in the latest version of
lvm2, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 504341@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
