_postinst_bsdflags: apply to $ROOT, not $D
David James [Thu, 28 Apr 2011 21:22:15 +0000 (14:22 -0700)]
Move preinst/postinst_bsdflags from bash to py
Moving these commands from shell to Python helps avoid an unnecessary
call to misc-functions.sh for the postinst_bsdflags. This improves
performance.

display_preserved_libs: load plib_registry
Since commit
7535cabdf2fab76fc55df83643157613dfd66be9, the
plib_registry is modified in a subprocess, and the parent
process' copy can become stale because of this. Therefore,
explicitly load it.

Add --nousepkg-atoms, --useoldpkg-atoms, and --reinstall-atoms flag
to Portage
reinstall-atoms accepts a space separated list of package names or
slot atoms. Emerge will treat matching packages as if they are not
installed, and reinstall them if necessary.
useoldpkg-atoms accepts a space separated list of package names or
slot atoms. Emerge will prefer matching binary packages over newer
unbuilt packages. This is useful in case you want to request that a
particular package won't be rebuilt from source.
nousepkg-atoms accepts a space separated list of package names or
slot atoms. Emerge will ignore matching binary packages.
