doc for 7.3 Under Kickstart Options, part --size says that --size must be specified even for an existing partition. I installed 7.2.93 into existing partitions but the generated anaconda-ks.cfg file did NOT have --size specified on the part statements (yes, they were commented out but even so).
Can you attach the kickstart file?

--size shouldn't be needed with --onpart
too bad in a way ... now I will bugzilla ksconfig since it requires size also.
IIRC, this statement was added to the docs because anaconda wouldn't parse correctly without --size with --onpart. Since katzj fixed this limitation, I have removed it from the docs. It will appear correct in the next release. Thanks for your report.
