My normal updating procedure is

EMERGE_DEFAULT_OPTS="--ask --deep --tree --verbose --jobs --load-average=5"
emerge --update --changed-use --keep-going  @world

I had mistakenly thought this would update all packages not at the
latest version (subject to package.accept_keywords, package.mask, ...).

I now realize that it only does this for the packages in world and then
follows the dependency tree.  So if package A in world is up to date, A
depends of B, and a new version of B appears, B will not be updated.

As a result eix-test-obsolete finds that I have packages installed that
are no longer in the database.

I could do 

emerge --update the-2-dozen-such-packages

Is that wise?

thanks,
allan

PS This system is in the midst of the multi-month bothwick "goingstable"
procedure.  I don't know if that is relevant to the decision.

[ subsequently he recommended using the latter choice ]
