[gentoo-portage-dev] Configuration files in a package

[Andrea Carpani]

Hi everybody.

Suppose I have a costom package that contains some executables, data,
lib and config files:

/usr/bin/foo
/usr/share/foo/data
/usr/lib/libfoo.so
/etc/foo.cfg

Is there a way to tag some package files as "configuration files" (in
the custom ebuild with a custom function maybe) so that once the package
is installed I can do something like

# qpkg --get-cfg-files foo

and obtain a list like 

/etc/foo.cfg

I'd like to have the same thing for library and executable files.

# qpkg --get-lib-files foo

/usr/lib/libfoo.so

Or maybe something that gives me a LIBS or CONFIG file in
/var/db/pkg/<category>/<app> filled with files that the ebuild tagged in
a special way.

Thanks.

Latest version of "equery" (app-portage/gentoolkit-0.2.0_pre10)
includes that feature. Not sure the manpage is up-to-date tho, so
you may want to have a look on the description on bug #43422:
http://bugs.gentoo.org/show_bug.cgi?id=43422

For config files, it should be something like this:
 # equery files --filter=conf foo
The definition of a config file is "a file that is in your
$CONFIG_PROTECT path" (see make.conf or make.globals, it includes
"/etc" and a few other dirs).

For executables, try:
 # equery files --filter=cmd foo
The definition of a command is "a file that is in current $PATH".
Thus, a user and the root may have different results if the
package has installed some files in /sbin or /usr/sbin.

There is no option for libraries, but you can try something like
that: 
 # equery -C files --filter=obj,sym foo \
   | sed '/^\//{/.*\.\(so\|a\|la\)[\.0-9]*$/!d}'
It will list files & links named "something.{so,a,la}[.version]".
A "lib" filter rule could probably be added to equery tho, all
that is needed is a correct criteria to recognise this files
(like a regexp match on there name similar to the one above,
or a`file | grep something` test, or a list of directories where
libs are supposed to be installed... well, something like that).

I can't talk for portage devs, but I doubt they are willing to add
db entries and modify portage just for that purpose.
