o debootstrap quer remover a pasta de destino, por quê?

Question

Eu usei no passado debootstrap para fazer o bootstrap dos sistemas Debian e Ubuntu. Mas desta vez, tentando inicializar um sistema Ubuntu a partir de um sistema de resgate Debian 6 (Nota: eu não tenho escolha sobre o sistema de resgate, então por favor não sugira usar o Ubuntu ou algo assim, ele não estaria disponível para mim). / p>

Considere a seguinte estrutura de pastas /target , que desejo usar para inicializar o sistema:

/dev/md0 on /target type ext4 (rw,relatime,data=ordered)
/dev/md1 on /target/home type ext4 (rw,relatime,data=ordered)
/dev/md2 on /target/var type ext4 (rw,relatime,data=ordered)

Agora estou executando o seguinte comando debootstrap :

# LANG=en_US.UTF-8 debootstrap --exclude=dhcp3-common,dhcp3-client,laptop-detect,tasksel,tasksel-data --include=bash-completion,sudo,lshw,tmux,mercurial,etckeeper,unzip,mc,htop,pciutils,usbutils,openssh-server,localepurge,unattended-upgrades --print-debs --variant=minbase --arch=amd64 precise /target

I: Deleting target directory
rm: cannot remove '/target/var': Device or resource busy
rm: cannot remove '/target/home': Device or resource busy

Estou executando isso como root , mas as últimas três linhas me enganam. Se eu tentar o mesmo, mas sem /target/var e /target/home , as últimas linhas mudam para:

I: Deleting target directory
rm: cannot remove '/target': Device or resource busy

Eu sou usando:

# debootstrap --version
debootstrap 1.0.42ubuntu0.1

de aqui e instalei-o via dpkg -i debootstrap_1.0.42ubuntu0.1_all.deb , que afirmava ser bem-sucedido. Eu também tentei instalar a variante buildd em vez da minbase one. O mesmo resultado.

O que está acontecendo aqui? Por que debootstrap tenta remover a pasta de destino?

Observação: também verifiquei a página man , mas não consigo encontrar uma opção para evitar essa tentativa de remoção.

Observe também que: instalar o chaveiro do arquivo Ubuntu não muda nada. Eu usei wget -O /usr/share/keyrings/ubuntu-archive-keyring.gpg http://archive.ubuntu.com/ubuntu/project/ubuntu-archive-keyring.gpg para isso.

    

Answer 1

Bummer, o problema parece ser um bug (?) em debootstrap . Quando eu executo o comando assim:

# LANG=en_US.UTF-8 debootstrap --exclude=dhcp3-common,dhcp3-client,laptop-detect,tasksel,tasksel-data --include=bash-completion,sudo,lshw,tmux,mercurial,etckeeper,unzip,mc,htop,pciutils,usbutils,openssh-server,localepurge,unattended-upgrades --print-debs --variant=minbase --arch=amd64 precise /target

Eu obtenho a saída (saída completa):

Agora estou removendo o --print-debs da linha de comando e, de repente, recebo uma mensagem de erro útil:

I: Failed to retrieve InRelease
I: Retrieving Release

E: Couldn't find these debs: mc localepurge htop mercurial

Uma mensagem de erro que não recebi no primeiro comando invocado. Isso parece um bug real. Talvez ninguém, a não ser algumas pessoas, use o argumento --print-debs , por isso nunca foi encontrado. Remover os nomes dos pacotes da lista no argumento --include , em seguida, inicia o processo de bootstrapping bem-sucedido (e do que parece até agora).

    

Answer 2

adicione --keep-debootstrap-dir à linha de comando (mesmo quando usar --print-debs ). Para impedir que o diretório de destino seja excluído.
