Thanks, will be fixed.

You don't have to delete any of the packages. ;-)
And it's the nature of a live-cd that package selection and copying
isn't that flexible.

As long as it does not stop it's nothing to worry about.
"Normal debian way of life." ;-)

That's not possible, think about the way grml2hd has to run.

This derives from the debian package, it's not a grml issue. And
such questions are important for some people. Just an example: If
you remove postgresql 8.0 who says you would like to remove you
postgresql database(s) as well? See the point? If you still think
this is a bug/problem please run reportbug against Debian's mysql.
In general: if you don't know how to answer a question just stick to
the default. This applies to grml's programs as well as to debian's
debconf (that's where such questions derive from).

Sorry, I don't have any idea what's going wrong here. Must be initrd

Sorry, don't know what you mean. :)

Yes. A new devel release (0.5-2) is available for grml-developers
and beta-testers. It includes all the updates of the last few weeks
(and including 2.6.14-grml).

Could you provide a screenshot please? grml-autoconfig is the same
as on live-cd so it must be an initrd related issue. (IMO too much
output is better than the other way around. Helps at debugging. ;-))

Quoting http://wiki.grml.org/doku.php?id=tips ->
| Boot grml via floppy disk
| Your computer can not boot from CD-ROM but provides a floppy disk?
| Take a look at btmgr (http://btmgr.webframe.org/) or sbm
| (http://linux.simple.be/tools/sbm), they provide support for
| booting from CD-ROM via a special floppy disk.
The grml-kernel does not fit with all its features on a floppy disk.
So you have to use such a specialized floppy disk.

Oh, I'm not yet sure. If you would like to get something like a
stable snapshot join the grml-betatesters (just fill out
http://grml.org/beta-tester/) and you will get access to 0.5-2.
> Thanks for this excellent distro and USB support.
Great you like it. :) Thanks for your feedback!
