I'm forking a thread on ks, because it illustrates something that's been
on my mind for a while.
When I boot CD to net install (which I suppose the OP is doing coz
otherwise it doesn;t make sense to head for other parts, media in hand),
I'd like it to spit the CD out as soon as it's not required.
Normally, I use PXE but just sometimes, I might boot from CD and then
install off a good ADSL connexion. Taking the CD ensures there won't be
an install loop. Waiting for it's tedious.
bts I've just been testing PX+KS (CentOS5.1) on a 3yo or so Pentium IV.
Takes a little less than 15 minutes, about what RHHL 7.2-3 took on
Pentium IIs fdr a similar install.
In contrast, XP's equivalent takes around an hour and despite the .SIF
file (equivalent to the ks) it insists asking more question. And then
it's ready to install the applications such as office software.
Good Work JK (who I think's been on it all that time) and crew.
It sounds like there's some process left around which is keeping the
device open. That would be the first thing I'd check. If nothing is
obvious from a ps(1), then you'll have to dig deeper.
lsof(1) and/or an `fuser -v` are typically used to track this down.
The trouble is that these aren't available from the F2 virtual
terminal. I'm going from memory at the moment, but I'm pretty
certain this is the case.
To use these utilities, you'll have to do something like the
following:
1. chroot /mnt/system
2. mount up /sys (Check fstab, it would be something like
mount -t sysfs /sys
3. mount up /proc
4. /sbin/start_udev
You should then be able to use lsof and/or fuser.
You can also now do all sorts of other nifty things.
Note that to exit this environment cleanly, you have to clean up in
the reverse order. Starting will killing the udevd daemon.
Hope that helps.

I've been using kickstart installs with Fedora and CentOS for
quite a while now. I boot the system with a cd and enter the
appropriate command at the BOOT: prompt and away it goes. I've
gotten used to being able to eject the cd from the system (using
the button on the drive) at the point where it is installing
packages. For some reason, with Fedora 8 kickstart installs the
cd is locked in the drive and I cannot eject it. I've tried going
to a virtual terminal and running 'eject /tmp/cdrom', but it
returns "Input/output error".
I'd like to be able to take the cd with me so that I don't have to
go and retrieve it later. Does anyone know how this can be done?
Thanks in advance for your help.
