I'm using some LVM commands in a %pre section of the config file to scan for and create the device nodes and they appear to be executed as indicated by their logs. However, the device node files don't get created, hence anaconda complains that it can't locate the partitions I requested in the "--onpart" directive and stops. Using the console at alt-f2, if I execute verbatim the exact same commands, the device nodes are created. The logs of running the commands manually are identical to those when run from %pre. Can anyone offer any help or advice? Thanks in advance. -Steve Herewith, some supporting evidence: Error on the console: Unable to locate partition mapper/vg00-lroot to use for /.
