Re: [OSR-users] cannot install comoonics

Hi Patrick,

the cdsl support is done with help of bind mounts and symbolic links.
During the boot process (inside the initrd), /cluster/cdsl/{nodeid} is 
bind-mounted to /cdsl.local. If you want e.g. /etc/sysconfig/network 
hostdependent, it has to be replaced by a symbolic link pointing 
to /cdsl.local/etc/sysconfig/network.
The administration of the cdsls should be done using following tools:

com-mkcdslinfrastructure (1)  - Builds needed infrastructure to create cdsls
com-mkcdsl           (1)  - make cdsl

Best Regards,

Mark
