[gentoo-user] Recompile Gentoo Environemnet

Hello Everyone,

what emerge parameters recompiles everything in my gentoo environment afer
changing use flags

emerge --update --deep --*newuse* world?

I issued a

emerge -e world


and I saw it was installing 450 things so I ctrl+c the process, did I
kill everything.

Anyhow I would like to recompile everything existing in the
environment in the safest manner.


Thanks in Advanced,
Ninus.

If you just changed the USE flags then yes, a emerge -DN world should
work.   The -N is the key part there.  I like to add in the -D just to
make sure the packes those use are recompiled if needed as well. 
Usually I run emerge -uvDN world which will also catch any upgrades as
well. 

ctrl=c should kill the entire process.

I personally use

emerge --newuse --update --with-bdeps=y --ask --deep --tree --verbose world

The with-bdeps makes sure that my subsequent
emerge --depclean --ask
runs cleanly.

--tree --verbose gives a (overly?) detailed output that I like.

Glad you mentioned the --with-bdeps=y because I have that in my
make.conf file.  Saves me some typing.  That options is good to include
as well.

You almost always want

emerge -avuND world

Which will find every relevant change you made and deal with it.

Don't forget 

emerge -av @preserved-rebuild with recent portage versions
revdep-rebuild -p -i followed by 
revdep-rebuild to find broken stuff and finally
emerge -a --depclean to clean out obsolete stuff that's hanging around

Don't run these blindly. Eyeball the output, understand what you are looking 
at.
