Could be rather unhealthy if the compiler optimizes code for a sun4u on an i386. :-) It will confuse some things, yes. e.g. buildworld and ports, and maybe some things at runtime.

I just found the reason: I'm too thick. :-/ I though all the letters had to be capitals, so I set UNAME_M instead of UNAME_m. The days my brain leaves me... :-) Thanks for the help!

He does a csup at least once a day and also makes a new world at least once a day. He is pretty nutty about that which is ok for some -CURRENT system, but he also does that on production systems. Now I don't want to judge him about that, but he is a bit sensitive about the output of uname. The version is very important to him. :-) The prank I want to pull is to somehow change the output of uname -m to read something different. The best thing would be to change that to something ancient like C-64, i286, i8086. Or, if only plattforms that FreeBSD supports are allowed, then mips, alpha or sparc64 on an i386. That should keep him thinking for a while. :-) I don't want to do any damage, so I just want to screw up the output of uname and the system should work normally apart from that. I realise that I may have to change some of the OS's code and that's not a problem. I just don't know where to look for this kind of thing and I don't really want to do too much reading just for a little prank. This guy is a really good friend of mine but sometimes get up my neck because I am much more conservative about updating my production systems. As you can see on this machine, I go along the lines of RELENG_6_2 which he can't understand. This should buy me a little peace and quite for a week or two. Getting access to his machines is no problem as I am often at his place. Can this even be done and if so how? See the manpage, and the UNAME_* variables.
