[gentoo-user] cloning + upgrade howto?

[gentoo-user] cloning + upgrade howto?

[Helmut Jarausch]

Hi,

I'd like to transfer a GenToo installation from old hardware to a new
machine (adm64).

I've a running Gentoo system which has exactly the same hardware as
these new machines but this system has much fewer packages installed.

Is it possible to clone this running Gentoo system, essentially
overwrite
/var/lib/portage/world
with the larger version of the old hardware except some 64bit related
packages and then run
emerge --keep-going -j4 -1 --ask --update --newuse --deep @system @world
on the new machine.

Or are the any snags?

Many thanks for sharing your experience,
Helmut.

Only one, portage will barf when you have a world file containing
uninstalled packages. Copy the world file from the other machine
somewhere other than /var/lib/portage and run

emerge -n $(cat /path/to/otherworld)

Those are my principles. If you don't like them I have others.

I've never seen that, and yes, I've been known to add a package atom to
the end of the world file when I wanted to update world, and add a
package at the same time (xfce4 was the last time I  think, a month or
so ago), and didn't want to do it in two commands.....

In that cases I was adding a whole DE, so was also changing lots of USE
flags, so wanted an emerge -uDavN world to just update all the use flags
at once.... echo "xfce-base/xfce4" >> /var/lib/portage/world followed by
emerge -uDavN world worked a treat.....

OK, that's changed then. The last time I transferred an installation,
Portage really didn't like having non-installed packages in world.

That's still two commands :) You can do it in one with

emerge -uavDN @world xfce4

Only if your portage supports @world, not sure if mine does yet :)

It should, unless you are woefully out of date.

Not true: the versions of portage that support sets (including @world) are 
all hardmasked currently.

Still? I unmasked them ages ago, but though that had all been sorted out
by now. But yes, sets are about the only recent portage feature not
supported by the stable version, my bad.

I believe the mask is still in place because of a couple issues with sets, 
as well as issues with FEATURES=preserve-libs.

I don't think so.
I'm using the bleeding egde portage since several months now without any
problems. These have been mask for 'political' reasons - see an urlier
thread of mine. We - the user - should be forced to test the previous
version. I think this is a shame and several people on this list
seemed to agree.
