Bug#930754: Warnings when using bzip2 or lzma

Cross-posted to 2 groups.

Package: initramfs-tools
Version: 0.133
Severity: minor

Hello,

I tested the different options for the COMPRESS variable in initramfs.conf
and noticed that when using bzip2 or lzma I get a warning when an
initramfs is created:

	"W: Unknown compression command bzip2"

. It is harmless though, compression succeeds just fine. So it's just
irritating.

Best regards
Uwe
