No idea. One simply needs to know, you have to set up your the discs
manually if you intend to, eg gmirror the / partition.
I think on geom@ Pawel once explained why this wasn't changed in
sysinstall, but I can't find the mail.

These are historically grown.

You can't. dump(1) and restore(1), that's all you've got.

Mirroring partitions on a already running FreeBSD is counter-intuitive
anyway.

Set the second disc to sane values, dump your partitions, set up the
mirrors/... in single-user mode (even for / but here only with the a
partition of the second disc), restore your dumps, boot the second
disc, add and sync a from the first disc.
Utilizing `tunefs -L` and glabel for /etc/fstab eases the pain.

Adding Raid 0/1/3/10 (plain and/or geli encrypted) via geom afterwards
to a fully configured system with wrong offsets is possible (done it
once, don't intend to do it twice), but there are many ways to shoot
your knee-caps while doing so.
