Hi Meelis!

Thanks a lot for the feedback!

I agree that this is a problem, there is actually a technical reason
for that which is the fact that the bootloader (or was it the
firmware?) is choking on the size of the installer image.

I did create some images for testing:

This is the new standard debian-installer which uses GNU screen when
installing over a serial terminal. I was sure there were hints on how
to switch between the terminals. It's an improvement over the previous
design as you couldn't switch terminals over a serial connection at

SILO is being phased out and replaced with GRUB anyway. The reason why
we're still defaulting to SILO and not GRUB is because not all patches
by Eric Snowberg have been merged upstream yet and are hence part of
the package.

See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854568

This is an issue with choose-mirror from debian-installer which does
not officially support Debian Ports at the moment.

The source code of the package in question can be found here:

This was an issue in debian-cd and has been fixed:

Once src:linux and src:debian-installer have been updated in unstable,
I will build new CD images where this issue has been resolved.
