commit 00dac020ca2a2d82c3e4057a930794cca593ea77

    sysv: convert sysv to use the new mount api
    
    Convert the sysv filesystem to use the new mount API.
    
    Tested by mounting some old sysv & v7 images I found in archives;
    there are no mount options, and no remount op, so this conversion
    is trivial.
