I used Gentoo for over a year, from at least early April 2020 until my migration to GNU Guix in early December 2022. Got into DWM, LTO, minimal systems. It taught me more than any other distro, and there's still a lot I miss about Portage and the Gentoo community. Still use `functions.sh` to style my personal Bash scripts. Functional package managers have not nurtured the same culture around diverse USE flag support and quality packages + docs, and I wish I could just glue them together. Some day.
