After a decade since the last time, I installed the latest

I have other systems so I can access the UbuntuStudio one from the
outside, I also have a backup image made with dd that I can read. Is
there any file I should look at? What other options avail?
The install was among the longest ones I ever did in a few years so
I'm not all that keen on repeating it unless inevitable :-)
Reinstalled, posting from it.
Thunderbird had this in my Sent folder though it had NOT been sent
so here goes again with some additional (sorry if both show up somehow).
The install wasn't all THAT long, about 50 minutes. What SEEMED long
was the reading-in of the entire DVD without a single word on the
dead-fish screen to say boo.
On a kernel boot line, you can use
TORAM=yes # The yes part may be ignored, but it might work OK
docache # Some distros use a different keyword
This causes the DVD to be copied to RAM. The machine must be big enough,
for ISO_size plus 1.5GB or so. That should cover the space required.
By doing that, during installation, the seek time is zero.
Yes, but the load time is 30 minutes :-)

Such a scheme works best, with high quality media. My Maxell disks
run at max read rate for a DVD. My Philips CMC are constantly
throwing errors, so the read rate drops to 1X and this is a disaster.
The Maxell are actually Ritek.
On a Canonical distro that requires computing checksums on every file,
the RAM mount again pays off for that phase of operation. You don't
really want to random seek a DVD and compute checksums like that,
right from the DVD. That would really suck.
if your machine only has 2GB of RAM (which happens), then you'd be
better off using a USB stick for the media in that case. Working
with an unbuffered DVD, is not for the impatient.

16 gb in my box, the installer is actually one function in the live
system so what was actually loading was the entire live system and it
loaded into ram (I think) which took a long time. The problem with that
was a total lack of feedback on screen, this should really be FIXED. At
first just a very regularly blinking DVD light so I thought the media
was dirty, I wiped it and rebooted. The second time around I waited it
out. Once loaded I clicked the installer which apparently just copied a
huge image to the tartget partition, I have NO IDEA when that image was prepared or assembled but it only took about 5 minutes to install. Other
than this it's a fairly slick install, I'm not used to the partitioning graphics though.
