[gentoo-user] Automatically make backups of removed packages

[Enrico Weigelt]

Hi folks,


is there any global option (eg. make.conf) to tell portage always
to do backups of uninstalled or overwritten packages ?


thx

The (binary) package content files. In something critical got 
removed or broken by accident (eg. toolchain or portage itself).
And this should be done automatically.

What is that you want to backup ? Your distfiles directory should have the tarballs, if you don't erase them.
And you can consult the emerge logs (or qlop -u if you have q) to see what you unmerged.

Not that I know of.

What you could do is always make a backup of all packages when they are 
installed with FEATURES=buildpkg. When you uninstall them, the last backup you 
made it already there.

If you keep the backups reasonably pruned, total size will be approximately 
the size of /usr and /opt together.

Or, you could just habitually quickpkg and package you think you might want to 
keep before you unmerge it.

If you mean binary backup, you can enable buildpkg in FEATURES and
wait for next+1 updates, then you'll have binary package of current
and previous version...

If you just want to know what was previously installed, but don't mind
recompiling, you can use the "demerge" package, which saves state and
allows you to revert to a previous state (emerge back to exact package
versions that were installed at a certain date and time). It can also
use binary packages if they are available (when used alongside
buildpkg for example).

There are also commands to create binpkg of an already-installed
package, if you have specific times you want this but not all of the
time.

I always build binary packages when I emerge them (i.e.
FEATURES=buildpkg).  That way if I uninstall something or it is upgraded
etc. I always have a copy).
