In RedHat Linux 6.1 there seems to be a bug in linux conf, and the IP alis funciton.. Atlest it wont manage to bring up the aliases.. I tryed compiling inn a new Kerlen (2.2.13) but still it wont work.. Besides, GNOME is and the system itself is rather "Usnable", Now I run RedHat 6.0 and it's running Stable...
this is fixed in the errata initscripts...
