Installation de rcconf.
vanvincq@Debian-Laptop ~ $ apt-get install rcconf vanvincq@Debian-Laptop ~ $ apt-cache depends rcconf
rcconf
Dépend: whiptail
Dépend: whiptail-provider
whiptail
Dépend: dialog
Dépend: sysv-rc
Dépend: perl
Dépend: perl-modules
Est en conflit avec: file-rc
rcconf est donc écrit en perl.
