/bin/preseed_command: return: line 23: Illegal number
Erreur.
Cette erreur survient à cause du retour ligne '\n'.
Solution Dans le cas présent, j'ai remplacé \n par \x0a
Exemple :
- preseed.cfg
d-i preseed/late_command string \ in-target sed -i.bak "s%^exit 0%/root/preseed/firstboot.sh\nexit 0%" /etc/rc.local ;
- preseed.cfg
d-i preseed/late_command string \ in-target sed -i.bak "s%^exit 0%/root/preseed/firstboot.sh\x0aexit 0%" /etc/rc.local ;
