Admittedly, a poorly worded on now that I read it again... what i
meant to say was:
"How many people do MANUAL ISO based server installs and would be affected?"
In a previous life, I did a lot of installs to a lot of servers
sometimes several times per day, and when I first started that team
they DID, in fact, boot CDs and manually deploy each one. This was in
a test lab that had several hundred servers, so you can imagine the
amount to time wasted doing manual installs, even if you were doing
assembly line installs across a full rack of systems at once (insert
30 CDs, Power on 30 servers, go to server 1, hit enter, server 2, hit
enter ... server 30, hit enter, back to server 1, select Install,
server 2, select install, and so forth).
So my first update to the infrastructure was to set up a PXE
environment to remove the need for booting via usb or CD. So the ISOs
were then net booted. Then, installations were moved to kickstart or
preseed and controlled by a simple shell script that would take care
of pretty much everything automatically (it was a very ugly
implementation of what MAAS looks like).
Sorry for the confusion, I didn't mean to focus on the difference
between ISOs and the MAAS images that are just blatted to the HDD, but
more the difference between any sort of automated install vs a manual
install where the user would actually hit this issue with having to
catch a boot splash. In my own experience, that is just a very small,
debugging corner case while the overwhelming majority of installs are
done automatically, fully scripted and hands off to save as much time
Anyway, as I said, it's more to satisfy my own curiosity about how
others are actually deploying OSs in the wild.
