Subject: [PATCH] Fix linux banner utsname information


utsname information is shown in the linux banner, which
also is used for /proc/version (which can have different
utsname values inside a uts namespaces). this patch
makes the varying data arguments and changes the string
to a format string, using those arguments.

best,
Herbert
