 You can't, not the way you are doing it.
 You want to launch a shell script for the user, but the user's
 shell is /sbin/nologin. This exits immediately without launching
 the script.

 Give the user a real shell.

No, I am not running the full Plasma desktop - although I had tried this on a

Do you mean copying the Kim4 files from

The --tree command didn't get rid of them. Those packages that you where able
to build conflict with other packages that would have been considered with the
- --newuse flag. So the conflict is still there waiting to be resolved.

Maybe portage could've been a little smarter and determine on the first command
that yes there is a conflict but I can still build these 3 packages with what
you already have. Or maybe that's a bad idea because you may have to rebuild 
some of those packages once the conflict is resolved and all packages updated.

Maybe the 1st command should've given you a list of skipped packages. That would
make it way less confusing and easier to resolve the conflicts. It is especially
confusing because instinctively you would expect the results with --newuse to be
a superset of the results without it.

Same behavior with 47.0.1.  Starting 47 in "safe mode" avoids the
problem, but starting 47 in normal mode with all extensions disabled
still crashes.

I downgraded to 38.8, and everyting works fine again.

I guess I'll stick with 38.8.

Or maybe it's time to switch to Chrome. :/

[gentoo-user] Firefox 45.2.0 segfaulting

[Grant Edwards]

www-client/firefox got updated this morning to 45.2.0, and now it segfaults
whenever you enter a character in the search field or the URL field.

Anybody else see this sort of behavior?

For the missing icons, is this inside a Plasma session? What's the
output of "env | grep XDG_"?

As for delete, did you check "Delete" in the services configuration?

I did a really quick test by copying the service files to the KF5
location (/usr/share/kservices5/ServiceMenus) and ran a couple of
operations and it seemed to work OK.

Exactly! Pointless minutia, unless someone has knowledge of how the code
has changed over the last few years, related to those flags that change.

emerge -uvDNp world
emerge -uvDN world
emerge -uDtv @world

For sure 'N' and 't' are the specific flags that cause the differences
in behavior.

 So it was a just a 'moral booster' and a general 'shout out' for those
devs. If I really cared, and I do not have time to (deeply) care about these
improvements, I'd go to github and look at the codes that have changed over
the last few years, specifically realted to those aforementioned flags.
So if you look here::

https://wiki.gentoo.org/wiki/Project:Portage

You can see the dev listing for the 'dev-port...@gentoo.org' whom
collectively are doing an excellent job:: and that's my point.

hth,
James

No, even without -p the first command wouldn't have done anything, because 
"Total: 0 packages".
There simple was nothing to do! The second command showed "3 Packages".

Sorry for the interrupting a big gurus, but in my humble opinion
the reason why there was no compilation while running emerge for
the first time is the -p option (pretend).

Um, -e is --emptytree, no? -t is just --tree.  But yeah, according to his 
first email, James did leave out -N the second time around ("emerge -uvDNp 
world" vs. "emerge -uDtv @world").

without -N or -t, portage considers just the list of packages on the
command line.

-N is newuse, portage also considers packages whose USE has changed.
-t is emptytree, portage also considers the entire tree and -u tells it
to not remerge things that don't need updating.

The input set for those commands differs, so the output set might also
be different. Those two commands you ran are not guaranteed to produce
the same results (although the often will).
