Bug#474346: Installer keeps asking to insert CD1
Hi Gilberto,
Sorry for the late reply, but as I already said privately, I needed some
time to think about this and to prepare some things.
As you have probably seen through the bug closure mail, I have uploaded some
changes that should fix your problem and also some problems reported by
others after additional changes in daily builds.
Basically I never expected that mounting a CD on two mount points at the
same time would be a problem. And in most cases it is not, otherwise we
would have seen a _lot_ more reports of installation problems with Beta1.
However, it obviously is a problem in some specific cases, probably either
hardware or kernel driver related. As both of those subjects are rather
outside our scope and as it is very hard to work on something like that if
you cannot reproduce it yourself, I have decided to structure things so
that that problem is completely avoided. At least for now.
Unfortunately there is not much I can ask you to test now as there are no
full CD or DVD images that have the latest code. They will only be built
after the current changes migrate to testing when we start preparing for
the Beta2 release. I may contact you again when we do though.
Partly to get things straight for myself, I've written a wiki page [1] that
explains the issue. You may be interested to read it.
Thank you very much for your report and the information you provided. It
definitely helped me to define the issue and to decide on the solution.
Below some comments on your last mails. Note that you can still reply to
this, even though the bug report is closed.
Cheers,
FJP

Yes, that is expected. Because you force the CD to be ejected, it is no
longer mounted on /cdrom, so the installer can no longer load the
additional components it needs to detect the Windows partition.

(These results were sent without gzipping the syslog file, so that mail
never made the d-boot list. It is included below.)

That is an interesting data point. I have never actually tried with DVDs
myself (they are just too damn big IMO :-). On the other hand, I cannot
really imagine what's so different between CDs and DVDs that they should
behave differently. There is certainly no difference in the way we produce
the images.
Did you try the CD and DVD in the same computer and in the same DVD drive?

Sorry, that was my mistake. You found the correct file.

That's exactly what I expected.

OK. I've explained that above. For this to work again, the DVD has to be
mounted manually on /cdrom from a debug shell. Basically you have to "undo"
the eject command you gave earlier.

That's probably because it tries to load three different components.

Same reason: that expects the DVD to be already mounted on /cdrom.

Same again.

Thanks a lot for those. What I can tell from the logs is that everything
worked as expected. There are no actual errors anywhere.
The thing is that as far as I know there is no good reason why that message
"Please insert DVD Binary-1" should appear. After all, the DVD is already
inserted and the fact that it is already mounted on /cdrom should not
prevent it from being mounted on /target/cdrom too.
But as the only difference is that during apt-setup (whet it was first
scanned) the DVD was not mounted on /cdrom while during pkgsel (when you
got that message) it was, so currently that is the only explanation.
