[gentoo-user] single package backup

[gentoo-user] single package backup

[Daniel Iliev]

Hi,

Let's say there's a new version of a given package. I'd like to make a
backup, update, test and if I liked the old version better restore.


What is (is there?) the "Gentoo way" to do that?

Let's assume you upgrade from package/foo-1.0 to package/foo-1.1. You can 
then use quickpkg to create a backup of foo-1.0, upgrade with emerge -ua 
foo, and test it. If you are not satisfied, mask the updated version 
in /etc/portage/package.mask, and emerge -uak foo again in order to 
downgrade. -k tells emerge to use the binary package built with quickpkg 
instead of re-compiling.

quickpkg foo (or quickpkg package/foo-1.0)
emerge -ua foo
echo ">=package/foo-1.1" >> /etc/portage/package.mask
emerge -uak foo

I'm not really sure what happens with config files, though.

Thank you!

quickpkg is exactly what I was looking for.

Thanks Alex, this is also useful to me. I'm fresh here.

You can also add buildpkg to FEATURES, then portage will create a binary
package for every package you install. It can use a fair amount of disk
space, but it means you can always roll back from a broken version, even
if you managed to break portage.

And there's also buildsyspkg which does the same, but for system packages 
only.

Yep, that feature is great and I use it to distribute binary packages
over several x86 systems but in this case I wanted to try something on
my only amd64 installation where buildpkg is not enabled.

So, the quickpkg solution was perfect for this "post factum" situation.
