[edit] -Ox CFLAG explenations,test,etc

I would like to see some parts of this section expanded. Particularly the part about CFLAGS. The article mentions that -Os can actually be faster than -03. Could some one expanded on this, explanations, tests, etc.?

Thanks, Chris R.

That would be rather hard to test for real, what the author probable meant is the excessive optimizations can make a binary larger, and on some system configurations a larger program that's optimized is slower than a smaller binary which isn't. Mostly because of loading times, harddisk access that sort of stuff.

[edit] eupdatedb not found

"TIP: I'd recommend emerge gentoolkit and then use eupdatedb && eysnc before re-emerging your system."

- This doesn't appear to work. I just did this exactly and its not working : 

>>> app-portage/gentoolkit-0.2.1_pre7 merged.
>>> clean: No packages selected for removal.
>>> Auto-cleaning packages ...
>>> No outdated packages were found on your system.
* GNU info directory index is up-to-date.
tim@beast ~ $  eupdatedb && eysnc
-bash: eupdatedb: command not found
tim@beast ~ $ su
Password: 
beast tim #  eupdatedb && eysnc
bash: eupdatedb: command not found

Has it been depreciated from gentoolkit ?

i dont, if it ever was: 
gentoo ~ # qfile eupdatedb
app-portage/esearch (/usr/sbin/eupdatedb)

[edit] /etc/locales.build

i read here (sry its german) that you can also save about 200Mb if you comment out all langages you dont actually need. means for me: 

gentoo ~ # grep -v ^# /etc/locales.build |grep ^.
en_US/ISO-8859-1
en_US.UTF-8/UTF-8
de_DE/ISO-8859-1
de_DE.UTF-8/UTF-8

btw: i edited the layout of this page. maybe you should have a look into FAQ_Write_an_Article before writing anything :)

[edit] use app-portage/portage-utils to find dubs

Sometimes it might be helpfull to do something like "qlist -IDva", which will list all the packages of which more than one version is installed.

[edit] In Remove Unneeded Kernel Sources

The command, returns: 

du -sh --max-depth=1 /usr/src/*
du: warning: summarizing conflicts with --max-depth=1

[edit] INSTALL_MASK

To keep gentoo away from installing unwanted files like Changelog.gz or Author.gz TODO.gz, just add following line to your/etc/make.conf

File: /etc/make.conf
INSTALL_MASK="Changelog.gz TODO.gz Author.gz"
