Hello,
We propose to add this feature to dpkg:
http://maemo.gitorious.org/maemo-af/dpkg/commit/72c255d86d37a40d24d33ed784e8f3fbde377427
Current alternatives:
1) DPkg::Post-Invoke { "if [ -x /usr/bin/debsums ]; then /usr/bin/debsums
--generate=nocheck -sp /var/cache/apt/archives; fi"; find
/usr/share/doc/packagename -type f -delete} (just an example)
(I still have to figure out which package got installed, and for that I
need to use the "version 2 protocol" between apt and dpkg that man apt.conf
writes about.)
The problem with the following Post-Invoke hook:
The files are first written to disk and only then removed. It is better to
avoid writing them to disk at all.
2) Split packages: It depends on the packager(s) and as a user I would like to
filter the installation in some way.
Dpkg is missing filter support in general.
(About the patch: A slight optimization could be achieved by pre-calculating
the prefix length, but does not really matter. It's by no means a bottleneck of
any kind anyway.)
I think it does not hurt those people who would not like to use this option,
but it is a benefit for those ones,
who are involved in the embedded market using dpkg on their devices (like Nokia
phones) or those in general, who would like to have a filter support.
Thank you in advance!
Best Regards,
Laszlo Papp
