Hey Roland, thanks for the reply!
Yes exactly, I wanted to have the base packages which are installed during the
debootstrap stage to be pulled from sid, because I was getting dependency
errors while using APT Pinning for specific sid packages.
The reason why this happened, with regards to mpv, is because the target
release (bookworm) packages installed by debootstrap included certain libs with
version numbers too low for the unstable release of mpv.
I tried to solve the dep errors by having the base packages pulled from sid
instead. One can actually achieve this by using `lb config --distribution
bookworm --distribution-chroot sid`
This will indeed install the base packages from unstable, while retaining a
bookworm target release and allowing the successful installation of mpv + deps
with APT Pinning and nothing else. However, if you plan on installing other
bookworm packages, chances are that once again there'll be dependency errors
because of the bootstrap base packages being from sid. (Same thing in reverse)
The only viable solution ended up being a chroot hook that specifically
installs with `apt-get install -t unstable`, as you mentioned.
This will automatically upgrade all the dependencies of mpv from bookworm to
sid.
APT Pinning does not automatically upgrade packages if newer versions are
available during a live build, because of the APT:Preferences commands given in
config/common.
That's why it will keep target release packages and simply return an error if a
package from another release has a higher priority and higher version.
Kind Regards!
