In number of options the "infrastructure" options are at most 20% of
the total.  The other 80% are individual drivers, hardware (like
network cards, serial devices, usb devices, video...) or software
(crypto algorithms, partition formats, codepages, filesystems...).
You're going to have a hard time slashing 90% of that.
