[gentoo-user] creating an image of the system

[Benjamin Block]

Hej folks,

I wonder what is a good way to create an image of a gentoo-system, so
that one can apply it later to the same or other computers.

In my case it is a rather simple setup: one partition, no encryption or
lvm. Its a debug-setup, so its only used for certain programming-tasks
and not for daily work, so no need for something fancy. The time I setup
that system I also used only conservative compilation-flags and
optimisation, so that it can be used on other CPUs (well, they have to
be x86_64 and have to have mmx/sse[23] - but I think every setup that I
intend to use this on will have these properties).

So I reckon that one could just use tar with permission-preservation and
some excludes like dev/sys/proc/tmp. But is this a good idea or is there
a better way to do this? I never cloned a gentoo-system, so thats why I
would like to be at least somewhat sure about it, so that I don't have
to reconfigure it later again, because I messed it up :D

best regards,
