The extra H4 files came from alpha.gnu.org/../debian-libio, future

It's true that this makes using jigdo difficult, but as you can see
from Attila's sid CDs and DVDs, it's possible.
For files that change very frequently, grep them out of the filenames
passed to jigdo-file so they end up in the template.
For other files (packages on the CD that become outdated and disappear
from the main mirror), one possibility is to set up an md5sum-based
fallback directory; for a "MD5Sum=http://foo/" entry in the jigdo
file, jigdo will first look in the main mirror for a file, then for at
So we need to know how much packages changed since creation of the
image, if the changing file group is quite the same, and how "fast we
are moving". If we can guaranty that certain packages do not change in a
fixed period of time, making stably usable jigdo files much more possible.
Otherwise we would need the fallback directory. But that would limit
mirroring of the packages and we would loose on big advantage, beeing
independant of a certain server to download / distributing network load.
Some statistics for the hurd-H4-CD1 image:
381 could not be fetched from the Deibian mirrors (of which 3 where
duplicates. Can this even happen?)
14 Packages* files,
4 Release files,
As I understand the system, that last two simply mean, the archive is
not hte same as on CD.
91 packages can be fetched from alpha.gnu.org,
154 packages could not ber found on alpha either. I expect them to be
~120 remain as non-package files. These are: docs, tools, TRANS.TBLs,
The remaining, Release and Packages* files should go into the template
as they will never be mirrored anyway.
When including the 154 not found packages with 0.3 Mb/package, I
estimate template to be about 50-70 Mb.
This would be a template that worked at least until yesterday ;-)
(At this point I'd like to thank my new friends grep, less and sed and
of courde the pipe :)
