APT snapshots: drop i386 architecture
This would save us lots of disk space!
depends on it though: we could ensure our custom APT repo has the
correct i386 version of syslinux, but I’m not sure if it’ll be enough:
apt-get update we run after enabling i386 there might fail given
no i386 indices will be available for most APT sources. Worst case, we
can simply publish somewhere the i386
/usr/bin/syslinux binary we
need, and download+check it without using APT.
I could find no other blocker.
