 |
|
Hi!
My /etc/portage/package.use file is getting a bit huge. Most of the time portage complains about necessary useflag changes to build any specific packages, I simply put them into package.use and forget about it. Since I like my system also small-ish, I am really wondering if there is any way to filter out those useflags for unnecessary flags?
Some years ago, someone in this forum provided a nice script which checks useflags in make.conf for obsolete stuff. Something like that is on my mind... Any ideas?

You have a few options.
Eix has a report about obsolete use flags,... maybe it even will update it, I don't know.
I also created enalyze in gentoolkit for general installed pkg db reports. It has a rebuild module that will create a new package.use file in your home directory. No need to run it as root. From there you can tweak it if you like and replace your existing one(s).
| Code: | | enalyze rebuild -p use |
for a screen report. Run without the -p switch to generate the file. There are some other options as well, so run the help or see the man page.
| Code: | enalyze rebuild -h
# or
man enalyze
|
There is also an analyze submodule that has several reports which can report how and what packages use what flags, how, etc.. It can be useful to decide which flags to make global by putting them in make.conf. Then run the rebuild submodule to create your new package.use.
It's useful for changing profiles too, and creating a new package.use to maintain your currently installed pkgs without change..

Eix does never modify any config files (it even does not have permissions to do so since it drops its permissions). Moreover, eix does not support useflags seriously: It just tests whether the packages occuring in package.use do exist/are installed/are listed twice. The latter two tests are not done by default (since often not desired); to activate it you must set
| /etc/eixrc wrote: | REDUNDANT_IF_IN_USE="-some"
REDUNDANT_IF_DOUBLE_USE="some" |
(see eix-test-obsolete -h). |
