═══ LA CORRECCIÓN DE FONDO: no es `pack`, son las IMÁGENES ═══
El SDD 19 y el 20 decían «inyectar el texto de la licencia en `hammer pack`, que es aguas
abajo del ArtifactHash y sale gratis». La conclusión sobre el coste era correcta pero el
SITIO estaba mal, y por una razón que sólo se ve leyendo el código: `pack` produce un
`.swm`, que es una RECETA DE TRANSFORMACIÓN sobre fuente pública y por diseño explícito
«NUNCA transporta binarios cocidos»; e `install` REPRODUCE construyendo, con cache-hit del
corpus, en vez de bajar binarios. O sea que **el canal de paquetes de hammer no distribuye
binarios** y la obligación de acompañar-el-binario ahí casi no aplica.
Donde sí aplica, con toda su fuerza, es en la IMAGEN INSTALABLE: su rootfs se puebla con
`hammer install` sobre un prefix y de ahí sale un USB/ISO lleno de binarios que se le da a
alguien. Ése es el punto de entrega. (La obligación del espejo de FUENTES es otra y sigue
entera: las recetas apuntan a URLs de terceros que se caen.)
═══ LO QUE ENTRA ═══
· `scripts/licencias-textos.sh` + `licenses/`: los 44 textos CANÓNICOS de SPDX
(spdx/license-list-data), uno por identificador realmente en uso — la lista se saca de las
recetas, no de un fichero escrito a mano que se desincroniza. 764K.
· `scripts/licencias-rootfs.sh`: escribe /usr/share/licenses/<pkg>/ con el texto de CADA
licencia de la expresión (`Unlicense OR MIT` ⇒ los DOS textos: en un OR el destinatario
elige, y entregar uno solo le quita una opción que el autor le concedió), más un
MANIFEST.tsv. Medido: 1,0 MB para el perfil `cli` de 44 paquetes.
═══ Y SOBRE TODO: ES UN VETO ═══
Sale ≠0 si algún paquete del rootfs no declara licencia. Un informe que no puede bloquear no
cambia lo que ocurre; esto corta el paso. Y se ganó el sueldo al primer intento: reveló que
los perfiles `base` y `cli` —los dos más simples, los que primero se publicarían— llevaban
10 y 12 paquetes con binarios y licencia desconocida. Curados los 10 que se podían afirmar
(doas, iputils, less, mandoc, procps-ng, rsync, strace, sudo, tree, usbutils); ambos perfiles
bajan a 2.
Esos 2 NO se rellenan a propósito, y quedan vetando:
· lsof — licencia propia del proyecto, sin identificador SPDX. Toca `LicenseRef-lsof` con
su texto, que ya viaja en el tarball (la receta instala su COPYING).
· tzdata — dominio público por declaración de sus autores, y SPDX no tiene identificador
para eso (es una AUSENCIA de licencia, no una licencia). Toca
`LicenseRef-PublicDomain` documentado, no forzar uno de la lista.
De paso: normalizado `GPL-3.0+` (sufijo antiguo) a `GPL-3.0-or-later`, misma equivalencia
documentada que la barra de Cargo. Y el caso especial que puse para `Linux-syscall-note`
(«las excepciones viven en exceptions/») era una suposición razonable y FALSA: SPDX las
publica en el mismo `text/`; ese directorio no existe.
