This > latter point probably requires some discussion first. I believe including broken disks will then fail to boot the degraded system (if not including --run). See bug#350710. Upstream dislikes including config files with the initrd. As I understand it for the reason that the initrd should then probably be rebuild whenever the original config file is changed. Why do including --add require more discussion? What is the drawbacks? See also bug#336514 for a related issue. thanks for the help with this. - Jonas -- * Jonas Smedegaard - idealist og Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ - Enden er nær: http://www.shibumi.org/eoti.htm
