Haha, just got frustrated with how much junk is on my machine and globally disabled perl, python, ruby, and a bunch of other stuff. Bad times ensued ;). But really, as long as you're fine with looking at failed builds to see what went wrong, you should be fine. You can set PORT_LOGDIR in make.conf to send all build logs into a location (mine is /var/log/portage) so that all logs get saved automatically, which I find helpful. Alec

thanks.
Here is a compromise. I started with USE=-* and then gradually
added stuff that was needed by most items. My rule-of-thumb is...
If adding a flag to USE reduces the number of entries in package.use,
then I add it. I.e. if...
* not having flag foobar in USE requires 6 entries in package.use, and
* having flag foobar in USE requires only 2 - entries in package.use
...then I move flag foobar into USE and put a few - entries in
package.use. I do want stuff like ncurses nptl nptlonly posix readline
threads for every app which can use it. Similarly, cpu-specific flags
should be in your USE. This effectively gives you a very customized
profile. By the way, you can make your own variables in make.conf, and
concatenate them, like in bash. In my make.conf I have...
USE_BASE=-* a52 aac bzip2 cxx fortran ncurses netifrc nptl nptlonly nsplugin
offensive openssl posix readline ssl threads vim-syntax zlib
USE_CPU=mmx mmxext sse sse2 sse3 ssse3
USE_VIDEO=X dga dri exif ffmpeg flac classic gif intel jpeg mng mp3 mpeg ogg
opengl png rtmp theora tiff truetype vorbis xcomposite webm x264 xpm xv xvid
xvmc
USE=${USE_BASE} ${USE_CPU} ${USE_VIDEO}
I can mostly copy this to another machine. ***WARNING*** the flags in
USE_CPU are specific to, and have to be customized for, each machine.
My Dell Dimension 530 dates back to June 2008. Newer Intel machines
will have additional cpu-specific flags, and AMD cpus will have their
own unique additional flags. Your set of flags may be different,
depending on what applications you use, and what you want to do with the
machine.

Re: [gentoo-user] USE flags handling
Portage profiles set some default USE flags, then some ebuilds also set defaults. Using USE=-* disables all of these. You can see the defaults I have noticed that some packages have flags that I have not set, but I though that they were the default flags for that package. You mean those flags will become persistence? Will be them written to a specific file? You will do that, but not in the way you hoped. Pick a profile that most closely matches your usage and then find tune from that by adding or removing USE flags. That's a lot easier than deliberately breaking things and then trying to work out how to fix them. I guess your way is better. I think it will be a good idea to stick to the base profile, and define the required flags as locale flags.

It breaks things. * Long ago, setting a useflag always meant adding things to the default. For some years now, we have use-defaults, which means an ebuild can set whether a use flag set not by profile and not by user is on or off. If you add -* to your use flags, you turn all default-on useflags off too (which means you may switch away from upstream defaults a lot). An example where this may lead to trouble: you end up with sys-devel/gcc[- cxx], i.e. a compiler that cannot translate C++. * The dependencies on specific Python or Ruby versions are controlled via useflags.

Thank you all. I have concluded that I should stay with the base profile. Although I need a desktop, but this decision will be closest to what I want in a harmless way! (at least less harm!) Then I will add CPU specific and very frequent flags to make.conf and gradually extend the package.use file.
