Portage handles SLOT updates by only considering the latest SLOT (unless
you say otherwise). If I issue 'emerge kde-meta' on my box, portage
wants to install kde-4.0.2 because that is the latest version (portage
always wants to upgrade to the latest possible version even without
SLOTs being involved). To update an earlier SLOT I have to use a minor
syntax tweak:
emerge kde-meta:3.5
The ":" is the signal to look for a SLOT. Portage will update to the
highest version in the 3.5 SLOT which happens to be 3.5.9 for me.
(Aside: all we need do now is hope and pray that no package ever gets
a : in it's name ... )
Quite obviously, in my case the following two commands are identical:
emerge kde-meta
emerge kde-meta:kde-4
In summary, the SLOT syntax is just a sensible extension of how portage
deals with ranges of versions. Compare these and it all makes sense:
emerge foo
emerge >foo-1.0.0
emerge <=foo-2.3.4
emerge foo:1
emerge foo:2
Hope all this helps and it now makes a little more sense :-)
I learned something today. I didn't know about the *:* for slots.
That's pretty cool. ;-)
I hope I don't forget what I learned today. :-(
