Installer offers to create software RAID arrays from partitions
marked as RAID members, but does not support raid10 which was a
show-stopper for the installation of this server with 4 disks,
intended to be almost entirely on raid10.
Switching to a terminal and issuing lsmod I could see the raid0, 1
and 5 modules loaded but no raid10. raid10 module was also not
present in the filesystem so I assume it is not supported.
Of course it is not possible to boot from raid10, which is why I
intended to create a small /boot in raid1, but I wanted everything
else in raid10.
In the end I booted from a livecd and installed by debootstrap.
Obviously a bit of a fringe case, but "it would be nice".
