[gentoo-user] Short question on eix-sync; emerge -up world

[Meino Christian Cramer]

Hi,

 I do a

 eix-sync; emerge -up world

 on a regular basis.

 Since some time there are many KDE-related items in the output of the
 above command, that are marked with "NS". 

 From the manpage of emerge I saw, that there are "new and sloted"
 versions.

 "Sloted" means something like "side by side with the old version".

 But: For me as user/sysadmin....what advantage I would have to
 install two versions of KDE-pakets ?

 Thanks a lot for every helpful reply ! :)
 Have a nice weekend!

I haven't found a use for keeping the old KDE next to a new slotted
version, so I unmerge the old one after the new installation is
successfully completed.  Of course I run (mostly) stable packages and
as a result KDE emerges usually work straight out of the box.  If you
run ~ARCH then you may still need the old version until bugs and
teething problems are ironed out.

That's just my 2c's.

The advantage is that you can test one before you remove the other. Or let it 
be up to the individual user which version (s)he prefers by having both 
installed.

Now they made it slotted because the different minor versions of KDE do not 
mix. If they allowed them to mix it would result in unpredictable bugs that 
would make supporting KDE a nightmare. So to avoid that they are mixed they 
had two options. 

One is to make them slotted like they did and which results in great 
flexibility. The *only* other alternative would have been to make them block 
each other and hence require that you removed the old version before you 
could even test if the new version were able to compile much less if it 
actually worked.

It means you can choose between the two versions, testing the new one
before removing the old. It also means you don't have to remove 3.4
before you install 3.5, which could render you without KDE for up to a
day, depending on the speed of your computer.

You have just given a use for having the two side by side. Without
slotting, you'd have to remove the old version before using the new one.
For example, first kdelibs 3.5 is installed and 3.4 removed, then
kdebase, etc. Meanwhile you try to use KMail, which is still at 3.4, and
it won't work because its libs have gone.
