Have a look at /bootmnt/. You need to run
 mount -o remount,rw /bootmnt
though to write to it - and I would recommend remounting read-only
before shutting down as well.

Two partitions are actually bad. Right now, I use vfat for compatibility
with Windows machines - Windows is very easily confused with USB drives
with more than one partition.
