I suppose that we could perhaps do something like treating `~` as the
bit that gets expanded into the codename bit, but it seems like a bit of
a niche interest, and that code is already overly complicated.
What you probably ought to be doing instead is specifying the option you
want via the `classes` setting (an alias for `auto-install/classes`),
and then implementing the behaviour you want by setting `preseed/run` in
a minimal preseed.cfg, and having a script do whatever you want in
response to the classes= setting you specified.
So your preseed.cfg would just be:
=-=-=-=
d-i preseed/run string start.sh
=-=-=-=
and your start.sh would be something like:
=-=-=-=
#!/bin/sh
. /usr/share/debconf/confmodule
db_get auto-install/classes
db_set preseed/include "${RET:-default}".cfg;;
=-=-=-=
(you might want to check that the value of $RET makes sense before using
it)
Then the real configs go in `default.cfg` and `alternative.cfg`
(assuming you're planning on specifying `classes=alternative`)
If that works for you, please say so, and then I'll see if I can find a
good place to add it to the docs as as an example (suggestions, and MRs,
welcome :-) ).
You may be able to get inspiration from here:
https://hands.com/d-i/
although the class handling there is quite deeply buried.
Here's a simpler example of using preseed/run to do odd things to D-I,
that while not involving classes, is easier to follow:
https://hands.com/d-i/bug/846002/
BTW `auto-install/classes` is reserved for users (it is not used by D-I
internally), so it's there specifically for you to implement whatever
scheme you like.
Cheers, Phil.
