I'm running Debian Buster where I build some packages with the devscripts package. I want to build these packages for the current stable Debian release (bullseye) without upgrading my system. I'm not sure where to start. Update my build packages? Set some flag in the build scripts?

You can use pbuilder for this; install it, then run

sudo pbuilder create --basetgz /var/cache/pbuilder/bullseye.tgz --distribution bullseye

to initialise the Debian 11 build tarball. Then use pdebuild to build your package:

pdebuild -- --basetgz /var/cache/pbuilder/bullseye.tgz

See the pbuilder tricks page on the Debian wiki for a more general solution; you’ll have to adjust it to match the current stable and oldstable.
