Bug#1035360: bookworm RC2 installation leaves luks encrypted system in unbootable state



Hi Paul,

and thanks for the report.

Oh wow, that looks bad. Unfortunately I'm mostly familiar with the
regular d-i installer, not so much with the live counterpart.

Can't agree with you more. (Even with a developer hat, the first time
one gets confronted with a LUKS system that cannot be unlocked leaves
traces… Still remembering that initramfs bug I encountered around 2010,
as if it were yesterday…)

FWIW: While I'm not sure about live images (and I won't check right
now), regular d-i offers a rescue mode which automates the painful
detecting and unlocking steps when it comes to LUKS stuff, so you don't
have to know about cryptsetup luksOpen and friends to get a shell into
the installed system.

Helpful data point, thanks.

Either it was forgotten or dropped by the BTS; please use reply-all,
and attach it compressed (to avoid hitting size limits on either the BTS
side or on the debian-boot ML side).
