Hi,
I've done this before and it could be done in both ways
without problems, but to avoid confusion in the install
and disk format step I nowadays prefer to do it in multiple steps:
1) install system with only the needed system drives.
2) when the system is installed and fully setup add the raid arrays one by one
3) assemble the array
4) modify /etc/fstab, /etcmdadm/mdadm.conf, update-initramfs
5) add scrubbing to crontab
6) add the drives to smartd.conf
7) reboot, check that array is up at boot
8) go to step 3 for the next array and so on until done.

Ciao,
Tito
