Hi,

whereas COMMAND_LINE_SIZE is used inside the Linux kernel and can be
adjusted there (it already has different values for different plat-
forms), Xen uses another constant, MAX_CMDLINE, at different places
where start preparations are done.  Unfortunately, MAX_CMDLINE is set to
a fixed 256 in xen/include/public/xen.h without consulting which value
is possible for dom0 kernels (linux/include/asm-xen/asm-i386/setup.h)
which can then lead to a cmd line cut-off.   Is there special reason why
this is the case?  



Regards,
