The script's body was never wrapped in an os_family template conditional
despite the header claiming it was 'guarded by the chezmoi template
engine'. So topgrade/chezmoi apply would run it on every box and die
with '/var/db/repos/gentoo missing' on arch/debian.
Wrap the body in '{{ if eq .os_family "gentoo" }}' / '{{ else }}' (same
pattern the arch-only chaotic-aur script already uses). On non-gentoo
boxes the rendered script reduces to a single 'skipping' log line.
Also fix two stale comments in the header (filename was 05, not 10).
Verified by rendering with --config override: arch → no-op log line,
gentoo → full body intact, both pass bash -n.
Three issues caught during tadbit onboarding:
1. run_once_00-install-bootstrap-tools.sh.tmpl (gentoo branch):
'gnupg' is ambiguous (app-crypt/gnupg vs app-vim/gnupg). Use full
category/package names: app-crypt/gnupg, app-crypt/age, etc.
The previous 'for p in age curl ...' loop fed short names to
emerge which printed '!!! The short ebuild name gnupg is
ambiguous' and exited 1.
2. run_once_20-install-user-packages-gentoo.sh.tmpl:
sys-devel/base-devel doesn't exist on Gentoo (it's an Arch/Fedora
concept; Gentoo's toolchain is the @system set which is always
installed). Removed base-devel from the package list.
3. Universal scripts (run_once_20 + run_once_40) were running on
gentoo and hitting either 'die unsupported os_family' (universal
20) or 'WARNING sway packages not configured for gentoo' (universal
40). Added early-return: 'if os_family == gentoo, exit 0' at the
top of each universal script so the gentoo-specific scripts
handle the box. (Same pattern the chaotic-aur script already had.)
4. run_once_10-add-gentoo-overlays.sh.tmpl:
The cached ~/.cache/eselect-repo/repositories.xml was corrupt on
tadbit (lxml.etree.XMLSyntaxError on every 'eselect repository
list' call). Added a sanity check: parse the XML with
xml.etree.ElementTree, delete if invalid, re-fetch.
After these fixes, the bootstrap on tadbit is expected to run cleanly
with --keep-going (the four failures above all become no-ops).
Tadbit (tadbit-gentoo, x86_64, gcc 15.2.1, TKG kernel) joins the
homelab as the 7th machine — the first gentoo box. Adds Gentoo
support to the bootstrap alongside arch and debian.
New scripts:
- run_once_10-add-gentoo-overlays.sh.tmpl: enables GURU overlay
via 'eselect repository enable guru' + 'emaint sync -r guru'.
Idempotent — skips if GURU is already at /var/db/repos/guru.
GURU is required because eza, lazygit, topgrade, and most modern
CLI tools only live in GURU (not main).
- run_once_20-install-user-packages-gentoo.sh.tmpl: emerge-based
user package set. Writes USE flags to package.use/ BEFORE
emerging so foot/wofi/waybar get the right features. Detects
missing packages via 'command -v <basename>'. Falls back to
the official curl installer for bun (no gentoo package).
- run_once_40-install-sway-gentoo.sh.tmpl: sway stack via emerge
with USE flags for X+wayland+tray+upower+wireplumber.
Updated scripts:
- .chezmoi.yaml.tmpl: os_family detection now also matches 'gentoo'.
Critical fix: Gentoo's /etc/os-release uses single-quoted values
('gentoo' not 'gentoo' or "gentoo"), and chezmoi's parser doesn't
strip them. Without trimAll "'", .chezmoi.osRelease.id returns
the literal string 'gentoo' with quotes, and the eq test fails.
Symptom: os_family silently becomes 'unknown'.
- run_once_00-install-bootstrap-tools.sh.tmpl: added gentoo branch
that uses emerge --sync + emerge (skipping if tree is < 1 day old).
- run_onchange_30-ensure-cargo.sh.tmpl: added gentoo branch for
bat (already installed by emerge, just verify), topgrade (GURU),
cargo-update (dev-util/cargo-update in main).
README: documented Gentoo-specific quirks (USE flags, GURU,
single-quote parsing, no binary packages).
