So, I thought that - instead of beating a deceased equine and complain that existing distributions do not install well on my hardware - I would sign up to test the next one.
I have LVM on top of an MDADM administered disk on top of IMSM fake-raid, the whole thing on an X86_64 motherboard.
On the MDADM disk, I have a logical partition for sticking a /boot partition on and in the VG I have an LV to put / on.
If / when there is an installer, please let me know and I'll give it a test drive
Since I have sacrificial partitions, all I need to back out the new install would be The Magic Script to run on the known good install from inside a rescue system - right?
