That simple program will tell you that an unsigned long is 4 bytes, or 8
bytes.
It is then a safe assumption - that if you get back '8', that you're
running a 64bit kernel, on a

Mainly chosen during "make config".
Processor info you see at /proc/cpuinfo
uname -m tells me the hardware type of the machine. Is this determined while
booting or is this the architecture I choose during 'make config'?
Can't I run a i386 kernel on a ia64 machine? I know something like this from HP-
UX. You can choose between a 32 and a 64 bit kernel when installing, s

uname(2)
It gives out various strings from which you must then deduce,
what kind of kernel is needed to r
