[gentoo-user] emerge -U?

[Willie Wong]

Can anyone tell me when emerge -U disappeared? 

I have never used it myself, but I just looked at "man emerge", and I
don't see that option anymore.

I have no recollection of -U at all. I've used -DuN for years. What do
you remember what you thought -U was doing?

--upgradeonly

meaning: if *best* available version in portage tree has lower version
number then the installed version, do not downgrade. 

For example, look at this bug report from 2004
 http://bugs.gentoo.org/36334
which refers to the --upgradeonly flag that is not in "man emerge" 
anymore, and 
 http://thread.gmane.org/gmane.linux.gentoo.user/86473/focus=87085
a post on this very list from June 30, 2004, also mentiones the -U
flag. 

Come on, I am only 25! I can't be the only *old-timer* who remembers 
this option!

-U was "upgrade-only"... I think it meant it would not downgrade a
package (even if a downgrade were required).  My guess is that it was
removed because it broke stuff lol.  I never understood why it would be
used anyway.  It's not usual that something needs to be downgraded and
when it is it's usually for good reason.

I'm 44 and I remember -U from 2005 (IIRC)

But I never used it so don't miss it. If I were the maintainer, it would be 
something I'd be removing real quick. It would arbitrarily override 
information in ebuilds, not allowing a downgrade that the dev determined was 
correct, it would apply to all packages to be upgraded or to none with no 
granularity. It would also cause all manner of blockers to kick in with an 
active tree.

You are better off doing this package by package with the various files 
in /etc/portage/*. At least with those you know exactly what effect is going 
to take place.

You are not alone.  I remember it too.  I even used it a couple times. 
I can't say it was worth it tho.  Oh, I'm 41.

I used to use -U round about 2004. Reason I used it was because I
emerge unstable packages by setting the ACCEPT_KEYWORDS environment
variable. I learnt better ways of doing it and started using the ~x86
branch, so my need for it disappeared. I remember seeing deprecated
warnings about it soon after I started using it, but I'm not sure when
it was removed.

I'd rather not go into my age :)
