Dear all,
while waiting for one gentoo box to finish with updating, i've decided to take care of my old work horse.
Following
https://forums.gentoo.org/viewtopic-t-1042252-start-11.html
i used the script from @Irre to sort out my /var/lib/portage/world file, which is kind of big.
If i understand the functioning of the script correctly, every package which would be cleaned out by emerge -p --depclean <package> should stay in the world file. Everything else "can be" removed.
I do know, that it is more or less up to me, what can be in there and what can be removed.
the results of the script:
"deselectable" packages:

For me it confusing that there are a lot of sys-*/* and dev-lang/* packages on the list. I do have a machine with a very small set of packages
and the world lists only the following sys-* packages
| Quote: |
sys-apps/mlocate
sys-apps/pciutils
sys-apps/systemd-tmpfiles
sys-block/parted
sys-boot/grub:2
sys-fs/btrfs-progs
sys-fs/dosfstools
sys-fs/jfsutils
sys-fs/reiserfsprogs
sys-fs/xfsprogs
sys-kernel/gentoo-sources
sys-kernel/gentoo-sources:5.10.52
sys-process/cronie
sys-process/htop
|
Thus i'm wondering which of the sys-* packages can be savely deselected with emerge --deselect.
Many thanks in advance,

blubberbaer,
A few random examples.
in in the @system set and should not be in world.
should be a dependency of something that needs rust to build.
More completely, as several packages can provide rust, packages that need rust depend on virtual/rust.
That in turn prefers dev-lang/rust but dev-lang/rust-bin works too.
It should not be in world.
| Code: | sys-devel/libtool
sys-devel/flex
sys-fs/udev-init-scripts
sys-libs/glibc
sys-libs/readline |
and others are all system set members.
Do you still use sys-apps/xinetd ?
You probably shouldn't.
You probably want to keep
| Code: | app-admin/syslog-ng
app-crypt/gnupg
app-emulation/libvirt
app-emulation/qemu
sys-apps/pciutils
sys-apps/smartmontools
sys-boot/syslinux |
and others. That last one is your boot loader :)
x11-base/xorg-drivers in installed because of VIDEO_CARDS and INPUT_DEVICES it should not be in world.
That's by no means a complete list.

Are there any on the list that you know you want? If so, remove them from the list.
Regarding the dev-lang, do you or may you have thought you wanted to write code with them? If not, check if they're a dependency of something else:
emerge -cvp <packagename>
-c safely tries to uninstall the package
-p only pretends to do so
-v will tell you what depends on the package, if anything
For example, I have dev-scheme/racket installed. Portage tells me that it is a dependency of app-editors/vim. This is only partly true. I installed racket and added the racket USE flag to vim.
Regarding app-shells/bash and the @system set that NeddySeagoon mentioned, emerge -cvp will show you that it is required by @system (probably among other things). That should help you go through the list. If @system requires it, it doesn't need to be in world.
For the sys-* packages, it depends. Several look likely to be part of the @system set. Other look like packages you probably wanted installed at one time or another... dmidecode, pciutils, parted, cronie, htop.
Check the descriptions of the packages to help determine if you want them. For example: emerge -s sys-apps/dmidecode$ (the $ at the end tells portage to look for the specific package, more or less).
If you're not sure, keep it, then come back with the hopefully much smaller list.
