The Linux 6.1 backports are built with udebs disabled, but it would
be useful to actually have them built and available even though
the default Bullseye installer uses 5.10:
I tried to build a Bullseye netboot image with an initrd including
the 5.10 kernel modules and the Linux 6.1 kernel for Bullseye.
Such a d-i image boots fine, but then anna attempts to fetch matching
udebs from the Debian repos and since src:linux-6.1 build with udebs
disabled the installer aborts.
While this should be a one-line change in the source package, there is
always some risk in doing this. And this change doesn't really seem to
be in scope for LTS.
Before replying to the report, I'd like to hear whether the LTS team
generally agrees that with that assessment.
