On RedHat 6.1 Installer occures the following Problem: While partitioning the harddrives, the installer/partitioner write one partition to primary and all others partitions to extended partition. The Problem is: The biggest partition (like /usr or /opt) is every time at the primary partition. (eg: /dev/hda1) Smaller partitions (like /) will be moved to the extended partitions (/dev/hda5) On an alpha-system is the bootloader Milo, Milo can NOT work with extended partitions. The root-filesystem must be on an primary partition. (eg /dev/hda1) But the root-filesystem have only 150 to 300 MB. If I want to write partitiontables, I have no chance, to put the root-filesystem to /dev/hda1 because all bigger partitions want to have this partition! So there is /usr or /opt or any other big filesystems every time on the only primary partition.
Issue is resolved in the latest installer (available in beta)
