Hello list,
I'm a sort-of newbie gentoo user and I just wanted to ask if what I'm
thinking is possible or if I'm just being stupid. But either way, I was
wondering if it is possible to export a list of all installed software
in emerge and use that to recreate on another gentoo install.
I have a bunch of PCs that are all similarly specced and I wanted to
create a minimal install "template" for all of them. If not, would it be
possible to pipe-in to emerge from stdin an output of all of the package
names that I wanted it to emerge?
I'm really sorry if this might be a stupid question. I'd appreciate any
guidance in the matter.
Cheers!
There is a file that contains all the packages you have installed. It
is located here:
/var/lib/portage/world
One could copy that file to another system and do a emerge @world to
install the same list of packages. Depending on what all you have
installed, it could confuse emerge and not be doable. In the past, I
had a copy of the file and I emerged them a few at a time. It's worth
trying by just coping the file tho. It just might work.
Someone a while ago gave me a tip along the lines of
emerge < /var/lib/portage/world
I was building a new system and they said this was a good way of getting
the new system to have the same packages as the old one. Mind you, I
think I'd now rather just print off @world and be choosy in what I
re-emerge.
Oh - and for quite a while I used the -b -k flags a lot, mostly emerging
on the slower system actually then installing the binary on the fast
one. Sounds odd, but the faster, newer system had a habit of crashing
during an emerge ... Both systems now gone to the Computer Centre in the
Sky :-)
Cheers,
Wol
