OK.  I'm so embarassed to admit I hadn't.
Now I have lvm-common and lvm2, and am wondering why it didn't get 
installed automatically by the installer, when it could see I had
LVM on RAID on my file system.  Perhaps because I didn't ask it to
make it available during the partitioning phase of the initial
minimal install.

However, I now have lvm-common and lvm2, ans still get the boot-time 
message

mount: special device /dev/VG1/LV1 does not exits
* Mount local filesystems failed with error code 96

So there's something *else* that has to be done.

I could try reinstalling on /dev/hda2 from scratch, and this time
telling the partitioner to mount my lvm partitions somewhere.
Maybe if I do that it will figure out what has to be installed for it?

I'm interested in getting the thing going, but I'm also interested in 
why it didn't work out of the box, so to speak.
