Bug#541248: initramfs-tools: Hard to debug lvm issues in cryptroot script
Package: initramfs-tools
Version: 0.92o
Severity: normal
Tags: patch
The /usr/share/initramfs-tools/scripts/local-top/cryptroot script used
with encrypted root does not print debugging information when checks fail.
This makes it hard to debug initramfs failures.
The following patch adds messages to the LVM section and enabled me
to debug issues with legacy lvm on Lenny.
