Bug#720162: debian-installer: Installed system is unbootable due to missing LVM support

Hi,

and thanks for your report.

Glad you could recover… Can you please attach the installer logs?
/var/log/installer/syslog in particular. Hopefully it's going to help us
find out what went wrong.

I know nothing about encrypted LVM (besides having used/tested it with
automated partitioning). Possibly, this bit didn't work:
| cbrulebois@Cygnus:~/debian-installer/packages$ cat partman-lvm/finish.d/aptinstall_lvm
| #! /bin/sh
| set -e
| 
| if grep -q " device-mapper$" /proc/misc; then
|         # Avoid warnings from lvm2 tools about open file descriptors
|         export LVM_SUPPRESS_FD_WARNINGS=1
| 
|         if pvdisplay | grep -iq "physical volume ---"; then
|                 apt-install lvm2 || true
|         fi
| fi

Not sure /proc/misc changed lately, and lvm2 didn't migrate to testing
recently, so I'm not sure what could explain a failure here, TBH.

Mraw,
KiBi.
