Netboot

[Phill Whiteside]

Hi Jackson,

Had a quick chat on -release... The reasoning is below:

(23:32:04) phillw: stgraber: I've had a bug reported... all the network
iso's are called mini.iso
(23:32:20) stgraber: and why is that a bug?
(23:32:44) phillw: well, try loading two of them, then using zsync?
(23:32:55) phillw: i686 / AMD64...
(23:33:22) stgraber: just store them on your machine with a different
filename?
(23:33:33) phillw:
http://archive.ubuntu.com/ubuntu/dists/raring/main/installer-amd64/20101020ubuntu195/images/netboot/mini.iso
(23:33:33) stgraber: besides, you can't zsync them as they are on
archive.ubuntu.com, not on cdimage
(23:33:53) phillw:
http://archive.ubuntu.com/ubuntu/dists/raring/main/installer-i386/20101020ubuntu195/images/netboot/mini.iso
(23:34:24) stgraber: sure, that's the filename that debian-installer has
always been using for the netboot images, changing that would break a lot
of things for close to no benefit
(23:34:36) phillw: So, they are being built daily, but in a totally
different naming schedule to the all the isos?
(23:34:43) stgraber: they're not built daily
(23:35:01) stgraber: they're built as part of a debian-installer package
build, so they're built whenever someone uploads a new debian-installer to
the archive
(23:35:36) phillw: okies, thanks.. i'll be able to reply to the tester for
which the names are causing problems
(23:35:39) stgraber: and they're built through the package build process,
not through the image build process, that's why they're on
archive.ubuntu.com as are all binary packages and not on cdimage.ubuntu.com
(23:35:55) cjwatson: And it's perfectly possible to supply a different
output file name when using zsync.
(23:36:26) cjwatson: Or rsync or whatever.
(23:36:40) xnox: phillw: zsync -o flag or wget -O flag.
(23:37:09) cjwatson: I'm responsible for those file names and I won't
change them.
(23:37:19) phillw: I see that they only have direct (http) entry for
download... sorry.. i didn't look deep enough into the issue reported by
the tester.
(23:38:14) phillw: cjwatson: is it possible to zsync when there is no zsync
link?
(23:38:36) xnox: phillw: yes.
(23:38:48) cjwatson: If it is, it will provide no meaningful benefit over
just using wget.
(23:38:49) xnox: phillw: it will redownload the whole file =)
(23:39:33) phillw: okies, I'll mark it down as "won't fix" :) Thanks for
clearing it up.

So, they are not part of 'normal' builds. I hope the above explains the
reasoning behind why it is done this way.

Regards,

Phill.
