I am experimenting with the Hercules mainframe emulator on my computer which runs Debian Linux 8 64-Bit.Per the instructions found here: http://www.josefsipek.net/docs/s390-linux/hercules-s390.html. I am able to reach the step where I partition and format the Direct Access Storage Devices (DASDs).  However, after creating a single partition on each DASD, I am not given an option to format the partition with a Linux filesystem such as Ext3, Ext4, or XFS.  I am only presented with these options:swap areaphysical volume for encryptionphysical volume for RAIDphysical volume for LVMdo not use the partitionIf I configure LVM, I can create two logical volumes (one for / and one for /home), but I still cannot format them with a Linux filesystem nor can I specify a mount point.  I am presented with these options only:1.) swap area2.) physical volume for encryption3.) physical volume for RAID4.) do not use the partitionI cannot proceed further with the installation because it will detect that a root file system has not been configured and formatted.  I have searched online for any other occurrences of this particular problem and I have not been able to find anything.My Debian system is configured from the stable branch only.  All package updates have been completed.  Here are the specifications for my system:Operating System:   Debian Linux 8.0 Jessie 64-BitKernel:             Linux 3.16.0-4 64-BitProcessor:          AMD FX-4100 Quad-CoreSystem Memory:      8192 MB (8 GB) DDR3 SDRAMEmulator:           Hercules Version 3.07I am installing Debian Linux on emulated mainframe hardware simply because I want to learn more about how mainframes operate.  I plan to perform an installation of the latest version of Multiple Virtual Storage (MVS) that IBM placed into the public domain, but I figured I would start with an operating system that I am more familiar with (such as Linux) before attempting the installation of a mainframe-only operating system.
