Pull request overview
Adds a new repo utility script to sync missing components from a Kiwi image .packages output into base/comps/components.toml, aiming to keep the component list complete and alphabetically ordered.
Changes:
- Introduces
scripts/add-missing-components-from-image.shto detect missing components from a.packagesfile. - Appends missing component stanzas to
base/comps/components.tomland re-sorts the file contents.

With set -euo pipefail, this missing-component pipeline will abort the whole script in common “no missing components” cases: (1) azldev comp list is likely to exit non-zero when a component is missing, and (2) grep exits 1 when it finds no matches. Both non-zero statuses will trip -e/pipefail before MISSING_COMPONENTS is checked. Consider explicitly tolerating these expected failures (e.g., azldev ... || true, grep ... || true) or, better, detect missing components via exit codes instead of grepping stderr text.

Component names that contain characters not valid in TOML bare keys (e.g. python3.14 or perl-Text-Tabs+Wrap) need quoting in table headers; base/comps/components.toml already uses [components.'python3.14']/[components.'perl-Text-Tabs+Wrap']. This script always writes [components.$comp] and also searches with a regex pattern that won’t match the quoted form (and treats . as a wildcard), so it can create invalid TOML and/or duplicates. Please add logic to emit the correct quoted header when needed and use fixed-string matching for existence checks (including the quoted form).

dnf repoquery ... $(cat "$PACKAGES_FILE" | sed ...) expands the entire packages list into the command line, which can hit ARG_MAX on larger images and is sensitive to word-splitting/globbing. Prefer feeding the package list via stdin/xargs (dnf repoquery ... --srpm --queryformat ... $(...) -> xargs -a/while read) and avoid the UUOC (sed ... "$PACKAGES_FILE").

Rewriting components.toml by redirecting directly to the same path (} > "$COMPONENTS_TOML") is not atomic; an interruption or error can leave the file truncated/corrupted. It’s safer to write to a temp file in the same directory and mv it into place after successful generation.

This won't be correct, as the components may be defined in different files; that's why my original command line I'd shared uses azldev comp list with -O json and a | jq ... pipe to properly query. That would also obviate the need for the more complex parsing below.
