This script regenerates the portage world file by checking the portage
logfile for all actions that you've done in the past. It ignores any
arguments except --help. It is recommended that you make a backup of
your existing world file (/var/lib/portage/world) before using this
tool.

Replying on Kindle. Short suggestion is recreate
/var/lib/portage/world by hand by adding what you know you want
installed.

Good luck,
Mark

AFAIK, Gentoo does not have a script or an option to back up the
world file and other associated files.

After I finish even a small update, I will run my own script
to copy /var/lib/portage and /var/db/pkg to another drive for
safekeeping. There may not be much point in doing so. If my
main HDD fails I will have to reinstall the entire OS, but
just in case of some freak accident that may affect the world
file I will make the backup.

My whole system I will backup once a week, and all very important
new data will be backed up (almost) immediately.

Regenerate world does ring a bell here though… unfortunately I have no internet connection for googling right now
perhaps something with equery

emaint world however is not what I think of, though it might be worth a try, dunno what it actually does, maybe it will just say it cannot find world

That's how I'd do it, except by using emerge -n instead of editing the
file by hand.

emerge -cp
emerge -n any packages in the list you know you want
rinse and repeat

Answering from computer now. A couple of ideas:

1) Copy one of my world files to your /var/lib/portage/world. Attached
at the end. This is for a typical KDE/nvidia desktop machine. Adjust
as you see fit. Run emerge -pvDuN @world and adjust the world file to
match your machines goals.

or...

2) I can't verify Neil's emerge -cp suggestion here as there's nothing
emerge wants to depclean but I suspect it would work fine. (Can't
remember when Neil last suggested something that didn't!) As an
alternative try

eix -Ic

which produces a list of all packages installed. Look for the ones
where the package names are green as they are the packages that should
be in your world file. All the gray ones are dependencies. Use Neil's
emerge -n to add them in.

HTH,
Mark

This is why I keep an empty world file and use /etc/portage/sets/
exclusively. I'm backing up /etc/portage anyway (package.use and
friends), so it just makes sense to have 'world' in there ;)

This fixed the problem. It generated some extra packages, but I fixed them.
@everyone, thanks for your replies. For some reason the this reply
wasn't sent earlier and got saved as draft.

How would you do that? I'm currently using ~amd64 and can't yet use
sets for some reason.

Then you probably need portage 2.2 for this. Which will never ever become
stable it seems, but I'm using it just fine for three years now. You have
to put this into /etc/portage/package.accept_keywords:

<sys-apps/portage-9999 ~*

Or just enable a specific version, and put that in your local overlay, if
you don't trust the updates which happen every few days.

Is emerge @preserved-rebuild (with FEATURES=preserve-libs) also a 2.2
feature? I like this most, I no longer need to use revdep-rebuild. I
always considered having to use it a bug, fixing broken things after
breaking them, instead of preventing breakage.
