I have saved a copy of Debian Live to my own github account to take a look at and have found some things that I never knew existed so I thought I'd ask about them and if they are usable. I also have some other questions relating to config settings.
1. In /usr/lib/live/build/config I have found an option "if [ "${LB_DERIVATIVE}" = "true" ]" yet I have, that I can remember, never seen it mentioned in any documentation. Where is the actual setting for this?
2. The options
# $LB_PARENT_MIRROR_BOOTSTRAP: set parent mirror to bootstrap from
# $LB_PARENT_MIRROR_CHROOT: set parent mirror to fetch packages from
# $LB_PARENT_MIRROR_BINARY: set parent mirror which ends up in the image
# $LB_PARENT_MIRROR_DEBIAN_INSTALLER: set debian-installer parent mirror
# $LB_MIRROR_BOOTSTRAP: set mirror to bootstrap from
# $LB_MIRROR_CHROOT: set mirror to fetch packages from
# $LB_MIRROR_BINARY: set mirror which ends up in the image
# $LB_MIRROR_DEBIAN_INSTALLER: set debian-installer mirror
. I would like to change the hard coding to
so the download is automatically from the closest-fastest mirror but I am unsure what files contain these options coded into them.
