Excellent point. When does mandatory end and optional begin. This must be
decided.

Do we intend to support a non-desktop configuration? I mean, is a
IP-Masquerading mail/news/router/diald configuration to be an option or
are we aiming solely at the desktop?

Ok, this implies other services ... networking of some sort, ppp is a
likely candidate. You now need a newsreader that works well over a slow
link or a local news spool and method of retrieval. So the question now
becomes the size of the install.  Are we to be CDROM only? Do we install
basic networking and allow FTP install?

Back to an X-less install.  Will that be a supported configuration? WIll
we have scripted configuration in addition to / instead of GUI
configuration for basic services? If GUI only, to what extent?  How does
the new newt/whiptail interface look compared to the old dialog? Is it
useful to configure BOTH configurations (if we are to have a non-GUI
option).

How about some choices for canned configurations? Examples being:

1) text-based server
2) user desktop
3) network admin desktop
4) software developer
... you get the idea

How about a compromise here, support in the kernel the IDE and SCSI
drivers that make a point to provide driver development assistance to the
Linux community.  This would mean cutting out about all but Buslogic SCSI
controller ( now Mylex ) support.  If a user wants trouble-free SCSI
performance, they can get a SCSI controller that supports Linux. In
exchange we tell our users that they have a better chance of good
performance by using these controllers.

I agree, the users should not be compiling kernels and we should not
encourage them to do so.

Brilliant! I have seen nothing in the docs that suggests that a loop
device file can not be on an MSDOS filesystem. The only drawback that I
can see is that I suspect that file is not needed after you have linux
installed so it detracts from space available for the linux partition
since you need to create that file before you run fibs.  

COMPROMISE: fibs the dos partition, create a linux swap partition. Make a
dos or ext2 filesystem in the swap partition. Use that as the loop device
file on install, once it is loaded you can mkswap that partition to
destroy it and mkfs the linux partition and continue on with the install.

Uhm, current Debian istall is for international keyboard configuration
right after selecting color or mono screen after booting but yeah, lilo
should be extended for internationalization ... a query in
linux.debian.i18n might be in order here.

I missed that post, would that be done on 1) startup 2) shutdown 3)
demand?

This is, I fear, going to be a major sticking point unless we attempt as
far as possible to emulate Win95 for PPP login.  Most ISP's support this.

NOTE: I can provide uucp via TCP for anyone intersted.  Allows you to
quicky connect to the internet, grab your mail and news and hang up no
matter where you are in the world.

Look at the S.u.S.E. X servers.  These support more hardware and are being
fed back into the XFree86 project. They will likely always be a step or
two ahead of XFree
