lsinitramfs not aware of COMPRESS in initramfs.conf

[Bela Lubkin]

Add "COMPRESS=xz" to /etc/initramfs-tools/initramfs.conf; now /boot/initramfs* will be xz-compressed cpio files. Then `lsinitramfs` fails:

$ lsinitramfs /boot/initrd.img-3.2.0-32-generic
/boot/initrd.img-3.2.0-32-generic

gzip: /boot/initrd.img-3.2.0-32-generic: not in gzip format
cpio: premature end of archive

Patch to follow.

In the patch, "--long confdir,help,long" should be "--long confdir:,help,long" (add missing ':')

@Bela: Thank you very much for this patch and helping to make Ubuntu better.

Please could you resubmit the patch with the specified change you mention in #2? Also, for parity for mkinitramfs, lsinitramfs should support the '-c' option so that the value of COMPRESS can be specified on the command-line. Note that an update to lsinitramfs.8 is also preferred to document the newly-added options.

Comment (unrelated to your changes): Ideally, mkinitramfs and lsinitramfs would be the same script which changes its behaviour based on its name to avoid any possibility of the two getting out of sync as has been demonstrated by the COMPRESS issue.

Fixed in Debian version 0.120 and Ubuntu version 0.120ubuntu1.

Actually this was fixed rather earlier in Debian, in version 0.100.
