#177112 — Having scanned set of installation DVDs...

I'm tracking down some problems related to chosen install options.
I expect to be making _multiple_ clean installs.
Besides /etc/apt/sources.list, where is information stored after 
having scanned the complete set of DVDs.

I wish to store it to a safe location for use after doing EACH 
clean install.
TIA

Perhaps there are more places, but the package lists are at least in
/var/lib/apt/lists one file for each source (or mirror). I haven't
packages from CDROM, but I'd assume that they might end up there
as well.

Moreover there's a list in /var/lib/apt/cdroms.list containing
references to the CDROMs themselves (what exactly is in there
I can't say, but I'd expect the gory details over there:

It looks to have everything. I'll discover whether or not it IS 
everything I need later this week.

I think it will be worthwhile to read the whole chapter. Only had 
a chance to browse its table of contents.

Thank you.

Didn't get to it as soon as expected.
Just copying /etc/apt/sources.list and /var/lib/apt/lists is not enough.
Using either synaptic or apt-get I get an error message telling me to run 
apt-cdrom so the cdrom can be recognized.
The information about what package is on which CD is present as it reports which 
CD it is looking for.

I've not yet read 
https://www.debian.org/doc/manuals/debian-reference/ch02.en.html#_debian_package_management_internals 
.

Don't know when I'll be able to follow-up further.
Thanks again.

How does look sheepish in ASCII ;/
One might think that being past three score and ten one might actually READ what 
one has LOOKED at.

  years ago i copied from dvds to a subdirectory
on an external USB drive.  it worked ok, but i did
have to tell in the apt sources list that i was 
using a file and not a dvd.

  i am pretty sure i used a "cp -r" to do it too...

  fwiw,  :)

I have that on my TO-DO list.
There's an additional step - creating packages.gz so apt related tools look at 
it as a large DVD.

  the package list is in there, should be no need
to regenerate it.

  if your apt sources list points to the right
directory (use file not cd or dvd in the list)
it should find it and use it.

  i saved a ton of disk io when i was testing
things out back then.

  i doubt the disk/structure has changed that
much where this wouldn't still work.

  if you need the specific syntax i used for the
sources list i can probably dig it up.  i think i
have backups.  :)

We have different goals/assumptions.
You are creating a directory for each CD/DVD.
I have a situation in mind that mounting more than one directory would be a 
problem. Thus my solution for Jessie would take 13 DVDs and create one humongous 
pseudo-DVD.
P.S. I've never been described as "normal", much less "typical" ;/

  but you do understand that i only had them copied
to one device, one mount point, one directory which
contained them all, but apt doesn't care, it scans
them all the one time when you update and then they
are available just like any other repository.

  really, i think you are doing more work than is
needed here for no real gain in anything that i
can determine.

  mounting the device as i did caused absolutely
no problems that i recall.

  each disk was an entry in the apt sources list,
but if i didn't need that device (it was an
external USB device so not always turned on for
use) i just commented out those lines in the apt
sources list.

Light begins to dawn. I just carefully read manpage for sources.list .
Seems that I "knew" things that just weren't so ;/
I have the morning free and will do some experimenting.
Thank you for your patience.

  i'm glad for that, especially if it does save you 
tons of needless bit moving.  :)
