This is actually easy:

1. Create everything you need on the first drive (ok, you don't need
*everything* - just the base system and partitions)
2. gmirror label myraid mydrive0
3. gmirror insert myraid mydrive1

This way, mydrive0 will be the "master", which would be replicated on
the mydrive1 hereafter. After the first sync is complete, they will be
equal and mirrored. If the mirror is your root drive, don't forget to
fixup fstab and add geom_mirror module to the loader before rebooting.
