Yes it is the same general issue.  But I moved from my "goingstable"
laptop to my fully stable desktop, hoping it would be clearer.
I did run the emerge world with -t on the desktop.  I am now temporarily
removing the package.mask entry and running it again.  The output is

Calculating dependencies... done!

I did not do this upgrade and with my package.mask in place, update
world says "nothing to merge".

The equery's give

When I started this project there were no related bugs in b.g.o.
I will investigate them

513842 - talks about a upower mask from the openrc perspective
513700 - is about stabilizing upower-0.99.0-r1
512252 - again a problem for openrc users
515228 - talks about upower versions and differences with different systems.

One phrase from the last bug is "Probably we need to document this
better, for example in the wiki."

So perhaps the package.mask is not terrible.
Would you advise I put the package.mask in a "goingstable" laptop and
try an update world?  I do have two laptops whose configurations are
"close", one is my main system.  I would first update world on the other
one.

thanks again,
allan
