Installing without blowing away GRUB/MBR

[Mason Loring Bliss]

Hi, all!

I'd very much like to install FreeBSD 10 in some new partitions on an
existing system. The existing system has Debian Wheezy on it, and I'd like to
install FreeBSD without blowing away GRUB. Does the FreeBSD 10 installer
accomodate this desire?

What I'm imagining is that I'll end up with a freebsd-boot partition with
stage1 and stage2 in it, and then a ZFS partition with everything else. (To
throw a curve, I want to set up mirroring, and I assume I want either
manually or automatically to end up with an equivalent freebsd-boot partition
on the second disk.)

Thanks in advance for clues or pointers. I intend, at present, for FreeBSD to
consume a decent chunk of my infrastructure, but I want to ease into it,
hence my not wanting to blow away existing Linux stuff as yet.
