Re: d-i on ancient hardware



Hi Adam,

Next time please file an installation report [1] instead of sending an 
email to the list.

Thanks for your elaborate report though. Overall I'd say your installation 
was successful.

Cheers,

You can run it from a windows 98 boot floppy. There is also drdos and 
freedos...

We should document it better, that is true (and ship a more recent 
version). On my TODO list, but fairly low down.

Could you please give us the exact message? I would guess it is a kernel 
message though, so nothing we can influence.

Already answered.

This is still Beta. We are working on that before the release, though as 
always opinions differ:

Not sure about that as IIRC swap is turned off again during partitioning. 
However, I'm not a lowmem expert. The most important part is not to load 
more modules than you strictly need.

We test releases at 32 and 48 MB. I'm not completely surprised that 24 MB 
does not work. We already know that the current lowmem levels need to be 
checked and probably adjusted.

I don't think IPv6 installations have ever really been tested. It would be 
great if you could do trace the cause of the problems and help us fix 
them. Please file specific bugs against the relevant d-i components if 
you find issues.
If you need help getting started with that, feel free to ask on the 
mailing list or in #debian-boot on IRC (irc.debian.org / OFTC).

We use wget for basic connection testing.

That should be a matter of enabling the relevant options in the busybox 
configuration.

A quick grep on the busybox config gives me:
CONFIG_FEATURE_IPV6 is not set
CONFIG_FEATURE_WGET_IP6_LITERAL=y

Looks like the first needs to be enabled...

Handling of the two buttons can indeed be improved in some places. It's 
not always as easy as it sounds to define correct behavior though.

Please tell us how to get a full tarball on a floppy or inside a netbooted 
initrd...

Please make sure you have very latest udev and initramfs-tools installed. 
If it still happens then, please file a bug report against 
initramfs-tools.
