I'm afraid that those use symlinks or hardlinks to run every
different personality. What my init does is more or less (no real
code):

pid=fork();
if (!pid) do_klog();
...
pid=fork();
if (!pid) do_slog();

So, in function do_klog() we would like to change argv[0]. Things
like busybox and the like uses symlinks or mechanisms like 'command
subcommand'.

I'll give a look at the microdistros, anyway :)) Thanks :)
