Description Chris Ricker 2002-02-10 17:15:19 EST
When doing a CD-ROM install, package installation works something like this (I'm
basing this on the system sounds alone -- I'll go poke the anaconda source in a
minute to see what's *really* happening ;-):

1.  CD-ROM spins up, hard drive is idle
2.  package is transferred to hard drive from CD-ROM
3.  CD-ROM spins down
4.  package is installed

(3 and 4 are more-or-less simultaneous)

Since modern fast CD-ROMs take a long time to spin up and down, the end result
is that a lot of time is wasted....

If anaconda transferred multiple packages at once from CD-ROM and staged them
temporarily, CD install would be faster

Matt any idea on how to keep the drive motor running?
Comment 2 Matt Wilson 2002-02-11 12:52:58 EST
Other distros have done a "while /bin/true; read from /dev/cdrom > /dev/null;
done" for this...

Deferring to future release.
Comment 4 Chris Ricker 2002-06-06 00:09:05 EDT
Now that it's new release time I'm reopening this (note:  I've not yet gotten to
try an install.  If the new beta is already doing this, then please close it

We have not had any further complaints about CDROM installs so I do not judge
this change is necessary.
