Hi.
I was intrigued few days ago to notice the 10 DVDs available from
jigdo.
In my memory, debian was only 3 DVDs... but I thought that it was
because stuff were bigger than before, or that there could be more
packages.
Now, trying to fetch the hashes, I used the FTP/HTTP page, and there
are
only 3 DVDs. I guess those are not the same ones, so those hashes
are
not usable, but it's not my question.
What is the content difference between jigdo and http ISOs? ( I know
what is jigdo and how it works, my question is about the content of
the
ISOs. )
Respectfully, if you're asking this, then you don't understand how
jigdo
works. What you asked is like asking what's the difference between
the
http and bittorrent versions. Nothing, it's just a different way of
getting the iso. Each approach has pluses and minuses compared to one
another.
Well, in fact, the only problem is that I did not took time to RTFM. I
deduced from the void that if there were only 3 images on http, it is
because their content differs.
In the case of jigdo, you download most of the iso via Debian package
mirrors. The benefit being that if you already have a local/fast
mirror,
you're only downloading a few MB from the internet for the templates.
Also, old images can be used to build newer ones, so you're only
downloading the changes.
It's worth noting that jigdo pre-dates bittorent, at the time it was
conceived, there really wasn't any other way to distribute the load
of
new releases efficiently. Personally I found it to be a brilliant and
really cool idea. Even with bittorent being available now, jidgo is
still very useful.

I personally prefer jigdo, because it reduces the amount of bandwidth
needed on the complete network unlike bittorent which only reduces the
server's one.
Speaking about torrent, it seems that there is a tool named debtorrent.
Maybe a /var/cache/apt/archive can be used to build an iso with jigdo? I
need to try this.
