Much much longer, when I was still on the anaconda team we had numerous bug reports about this (esp during RHEL-6 testing), in many cases people filed bugs with a description along the lines of: "Installation DVD does not boot", because it took so long they thought the install was just hanging forever. > How many such machines? I've no hard numbers but enough to generate numerous bug reports during the non public testing phase of RHEL-6 alone.

Yes the hang is not guaranteed to be there, or to take very long, but often it is there, and sometimes it takes very long (which is the real problematic case). If you're really interested in seeing this fixed go talk to the kernel guys: anaconda loads the floppy driver by default when booting of the install DVD, because of driverdisk support, thus the anaconda team has been getting its share of bug reports wrt this. But AFAIK there are no such issues in RHEL-5, where we auto-load the floppy driver too, so something has changed in the kernel causing the hang when no drive is attached to the controller. I could swear I filed a bug against the kernel about this regression, but I cannot find it. > Leaving known-working hardware unusable at install is just rude and > irritating when it is needed.

Is it delays bootup by up to 10-30 minutes on various modern systems a good enough justification?
