I'm in the process of downloading and installing gentoo and as I was
looking over the install directions I noticed that the recommendation
is for the boot partition to be ~100 megabytes.  I'm wondering why so
large?  On one of my linux boxes the boot partition is 4 MB and I'm
only using 36% of it.  I know discs are cheap but 100 MB seems like a
lot of overkill and wasted space.
