Bug#839890: please give a tool (or document how to) unpacking an initramfs with microcode prepended

[Marc Haber <mh+debian-packages@zugschlus.de>]

Package: initramfs-tools
Version: 0.125
Severity: wishlist

Hi,

the new method of prepending a CPU microcode fix to the initramfs is a
nuisance when debugging an initramfs. Having to peddle with dd and
guessing (?) the correct offset in a situation where only a tiny part
of the system might be available or one is working from a rescue
system is not nice.

Please consider providing a tool which can unpack an initrmamfs with a
single call of the tool even if CPU microcode is prepended.

Thanks!

Greetings
Marc
