At the moment, I am considering the following paths
1) spending several hours checking out the ~amd64 packages I
emerged, to see if they are available in stable, and which
dependencies can then be brought back to amd64. As spare
time is a rather scarce resource for me, I don't want to do
this unless absolutely necessary
I run a mostly stable x86 system with specific ~x86 specified in
package.keywords. I hit the same problem you have so wrote the
following perl script to help manage package.keywords. You will
need to specify your ~arch in the $arch variable. Place the script
in /etc/portage directory. Run the script from /etc/portage directory.
Note, I always save a copy of package.keywords before running
the script just to be safe. Here's how I usually run it:
royw-gentoo portage # pwd
/etc/portage
royw-gentoo portage # ls
check-package-keywords.pl mirrors package.mask
package.use sets
find-test-kde package.keywords package.unmask profile
royw-gentoo portage # cp package.keywords package.keywords.save
royw-gentoo portage # ./check-package-keywords.pl >package.keywords.new
royw-gentoo portage # ls
check-package-keywords.pl mirrors package.keywords.new
package.mask package.use sets
find-test-kde package.keywords package.keywords.save
package.unmask profile
Then I examine package.keywords.new. If I like it, then I can simply
replace
package.keywords with it.
Here's a sample output:
app-admin/eselect ~x86
app-admin/eselect-opengl ~x86
app-cdr/k3b ~x86
app-crypt/gpgme ~x86
# NOT INSTALLED app-emulation/wine ~x86
app-misc/beagle ~x86
app-office/openoffice ~x86
app-portage/gentoolkit ~x86
# NOT INSTALLED app-portage/kuroo ~x86
# NOT INSTALLED app-text/evince ~x86
app-text/iso-codes ~x86
