Alpine Linux - como eu defino pacotes para carregar na inicialização?

Question

Parece que o Alpine Linux carrega pacotes quando é inicializado. Como adiciono o openssh aos pacotes que são carregados no momento da inicialização?

Quando eu estou logado, eu faço "info apk", que lista 16 pacotes da seguinte forma:

localhost:~# apk info
musl
busybox
alpine-baselayout
openrc
alpine-conf
zlib
libcrypto1.0
libssl1.0
apk-tools
busybox-suid
busybox-initscripts
scanelf
musl-utils
libc-utils
alpine-keys
alpine-base
localhost:~#

As seguintes mensagens do log de inicialização mostram esses 16 pacotes sendo carregados:

Answer 1

Assumindo que você está inicializando via USB, e você tem o lbu configurado corretamente, depois de instalar o openssh você deve executar:

 lbu commit

Isto salvará o diretório / etc no arquivo de sobreposição apkovl em /media/usb/yourhostname.apkovl.tar.gz

Pacotes instalados na inicialização estão localizados em / etc / apk / world, e quando você salva com "lbu commit" este arquivo também será salvo.

Para o registro, para verificar se o lbu está configurado corretamente (ainda assumindo que você está inicializando via USB), execute:

 cat /etc/lbu/lbu.conf | grep LBU_MEDIA

deve retornar:

 LBU_MEDIA=usb
