Re: [PATCH 1/1] bugfix: isar-exclude-docs delete man folders but some packages expect that folders

[Henning Schild <henning.schild@siemens.com>]

Hi,

you could simply not install "isar-exclude-docs", it is kind of a hack
which removes files that are very likely not needed. You found a case
where one file is needed after all.

Whatever we do we have to keep the postinst and the
/etc/dpkg/dpkg.conf.d/ snippet in sync. So you can not decide to keep
directories in one approach and drop them with the other.

The snippet is a one-to-one copy from ubuntu Docker containers, would
not want to fork it. So if we have to change it, we should also report
that to ubuntu.

Long story short, i think it will be a rather trivial fix in the
postinst of that java package. That very java package might show the
same problem in a ubuntu container ... which would be a nice repro to
motivate the maintainer to take a patch which deals with a file missing
... that in a plain debian would never be missing.

So i would say someone has to open an issue on salsa, maybe an MR.
Mention isar-exclude-docs and ubuntu docker images as examples where
the files and folders can be missing.

In the meantime you can not install isar-exlcude-docs, or install the
java package before it, or patch that postinst locally by rebuilding
the java package, or write a dummy package that does an "mkdir" in
postinst and install it after exclude and before java ... i think just
installing the docs is the easiest and will not cost you too much space.
