Qual pacote é responsável pela conclusão do bash para systemd / systemctl no Ubuntu?

Question

Eu tenho o Ubuntu 16.04 instalado localmente, e ele tem conclusão bash para systemctl subcomandos por padrão. Mas quando eu inicio uma instância do Ubuntu Server 18.04 no Digital Ocean, não há conclusão do bash para os subcomandos systemctl . Eu esperaria algum pacote ausente como systemd-completion , mas no meu Ubuntu local eu tenho apenas esses pacotes instalados:

ii  libpam-systemd:amd64                          229-4ubuntu21.2                                          amd64        system and service manager - PAM module
ii  libsystemd0:amd64                             229-4ubuntu21.2                                          amd64        systemd utility library
ii  libsystemd0:i386                              229-4ubuntu21.2                                          i386         systemd utility library
ii  systemd                                       229-4ubuntu21.2                                          amd64        system and service manager
ii  systemd-shim                                  9-1bzr4ubuntu1                                           amd64        shim for systemd
ii  systemd-sysv                                  229-4ubuntu21.2                                          amd64        system and service manager - SysV links

e trabalhos de conclusão. O pacote bash-completion está instalado nas duas máquinas.

Além disso, em /etc/bash_completion.d/ da minha máquina 16.04 local, não vejo nenhum arquivo de conclusão systemctl relacionado

Então, qual pacote devo instalar para obter a conclusão do bash para os subcomandos systemctl ? Talvez eu deva ativar alguma coisa nas configurações do bash em algum lugar?

    

Answer 1

Eu encontrei essa resposta primeiro, descobrindo qual pacote fornece systemctl :

$ dpkg -S $(type -p systemctl)
systemd: /bin/systemctl

Então, olhando o conteúdo do pacote systemd , vejo:

$ dpkg -L systemd
