I have set up a system with just raid 1 arrays for everything (including
/) with SL6 and have seen only one issue.  The first boot after install
fails, but this can be dealt with by running a live dvd/cd and then
rerunning grub-install.  I think the fully raided setup seems to confuse
the boot installation and the boot sector gets installed on one of the
two disks (the wrong one in my case).
