Package: debirf
Version: 0.37
Severity: minor
I'vve been looking for this issue for several days: our debirf-based
system generally works well (and debirf is a great tool!). However I get
one specific system kept failing to boot.
When I break in the first-stage loader, I see that rootfs.cxz has the
right size but an incorrect md5sum (compared to the one in nest/ , and
compared to the one extracted from the initrd.cgz file on the USB device
I boot from).
Eventually my workaround was to replace the compressor from xz to gzip
(See attached patch). I did verify that the issue is not the amount of
memory in the system, as the same image boots fine in KVM with slightly
less memory.

Subject: [PATCH] debirf: support gzip for nested rootfs
Add configuration variable DEBIRF_COMPRESS, defaults to "xz".
May also be set to "gzip". This is the compressor to use for
the nested rootfs.
For the sake of simplicity, the name of that file remains rootfs.cxz
regardless.
Gzip-compressed images are noticably larger (roughly 150% in my case).
However we had a case of an odd corruption of the xz image when the
compressor was xz (on one specific system, with an Atom D525 based Intel
board).
