Package: live-build
Version: 4.0.3-1
According to the documentation http://live.debian.net/manual/4.x/html/live-manual.en.html#380
--mirror-chroot-backports should control the backport mirror, however when using this option it fails.
$ lb config --distribution wheezy \
--mirror-bootstrap http://my-mirror/debian \
--mirror-chroot http://my-mirror/debian \
--mirror-chroot-security http://my-mirror/security \
--mirror-chroot-backports http://my-mirror/security
[2014-11-19 11:25:10] lb config --distribution wheezy --mirror-bootstrap http://my-mirror/debian --mirror-chroot http://my-mirror/debian --mirror-chroot-security http://my-mirror/security --mirror-chroot-backports http://my-mirror/security
lb config: unrecognized option '--mirror-chroot-backports'
If this option is excluded then the backport packages are pulled from the default debian mirror.
Cheers,
Craig.
