Services on Gentoo on Xen on RPI
Set it up.

Portage package changelog news reader thing
Software that will monitor changelogs, news, README, etc. on a per package basis and provide those changes to system admins.

For example, WireGuard support was just added to NetworkManager's interface. This is visible in in the NEWS file (the ChangeLog file seems abandoned since 2008).

This could potentially be handled in an or even a GLEP ultimately, since each project's changelogs may be a slightly different file, and on package upgrades it would seem one of the only sane ways of dealing with the new parts is to diff the newly added text and display that in a viewer. The ebuild could define which file Portage should 'watch' for news updates, then diffs of that file could be tracked by enabling a specific Portage feature  or some such thing.

Package build time calculator
Write code that will determine how long it takes a system to build a package, including the sum of all dependencies back to (and including) the toolchain. Think recursive.

Uninstall unused packages and/or programs
Research:

The Android (at least v12) has a few nice features that are helpful to manage privacy risk via app permissions and manage disk space. The OS will routinely collect information on the frequency of how often an application is used and, if not accessed by the user, restrict privileges to the application. It also will deactivate applications that are not used in a certain time window, although it does not seem to recommend they be uninstalled to free up disk space. It would be nice to have a similar feature on Linux systems: something that can show the last time a user (root included?) accessed/ran binaries from certain packages. There may be existing projects (QUBES?) like this already that provide the same or similar features.

make localmodconfig test
Test on a bloated kernel. See if it boots properly...

Ghost kernel
May be fun and challenging pproject to try to get more userspace processes running on Ghost kernel.

Root file system on NFS
Hmmm...


 * CONFIG_ROOT_NFS

Prefix under cygwin
Does Gentoo run under cygwin on Windows? This article seems to say it works...

Funtoo
Install Funtoo.

KVM/QEMU
Placeholder for commands I use to create VMs (testing).
