[gentoo-user] Want same ol' gentoo on new box

[Mike Markowski]

I'll be changing jobs Monday and want to be sure I bring along enough to
easily rebuild the sort of gentoo set up I currently enjoy.

After installing, will it be enough to use my current
/var/lib/portage/world and /etc/make.conf followed by 'emerge -uDf
world', etc., to get me going?  Or am I overlooking other important
system files?  (I'll remember to remove hardware dependent world entries
like graphics card drivers.)

Thanks!
Mike

Not exactly - you can't just copy /var/lib/portage/world, since portage
will complain about packages in the world file not being installed (at
least, that was the behaviour not long ago and I don't imagine it's
changed).

You can however copy /var/lib/portage/world to some other location on
your new computer, and do something like emerge `cat oldworld`.

You might want to copy things other than just /etc/make.conf from your
current install - if you've edited any config files (say /etc/vim/vimrc,
for example). I can't think of anything you'll definitely want to copy
across when changing computers, just stuff that you know you've edited a
lot and don't want to loose. (Oh, and I assume you know that you might
need to have a different make.conf to before depending on how different
the 2 computers are).

Actually, you can replace your world file provided you use "emerge
--emptytree --deep --newuse world", and portage won't complain that
packages aren't installed as the emptytree tells portage to (rightly
in this case) assume nothing is installed yet, including portage
itself.

Oddly enough, I just added a package that I don't have installed to my
world file, and did emerge -uvD world and it didn't complain (or remove
it from my world file). I know this hadn't used to be the case though.

So yeh, I guess you can just copy the old world file across and do
emerge -e world.

I think that there may be problems with adding a package that had
dependencies that you don't already have installed.

Adding a package, as you did, that has all dependencies already satisfied on
your system probably would work.

But I'd still be worried that adding a package that does not have
dependencies satisfied to the world file would not be a good thing (unless
of course you are using the emptytree option).

I don't see why it should cause a problem. Portage is quite capable of
calculating the dependencies and installing them. The situation is no
different from uninstalling a dependency of an installed package. The
next emerge --deep world will reinstall it.

Well, I only did it to see what would happen.

I also tried moving /var/db/pkg to somewhere else and did emerge -uavD
world, which had the same affect as doing emerge -ae world normally.

So, my original advice was wrong it seems (well, more out of date than
wrong, since I tried to do what the OP wanted to do a while ago, and
portage complained about things not being installed). That said, it
would still be one way of doing it, just not the simplest way.

Did a similar same thing about two weeks ago.

but found it better to copy the world file, make.conf 
and /etc/portage/package.keywords (if you have it) file, and the entire /etc 
dir to some other place, then install from stage three, put package.keywords 
and make.conf in place and do 

cat /someplace/world | xargs emerge -avD

then get a beer, chips and a movie (unless you have some insane SMP system).

after that copy over everything you need from your old /etc.

and there you are.

worked like a charm.
