Indeed on the same machine and with same config? It's strange, I never saw
this incompatibility, and I can't find bugs in the code able to produce this
(with a quick look). Could you check on your part?

Which are them? It should be setuid root and executable...
However, since:
# perror 2
OS error code 2: No such file or directory
Uml is saying it didn't find uml_net, or some of its libraries, not that
there's a permission problem.
Possibly it's lying and printing the wrong code, dunno. But from current code:
arch/um/os-Linux/helper.c:helper_child
execvp(argv[0], argv);
errval = errno;
printk("execvp of '%s' failed - errno = %d\n", argv[0], errno);
it seems not (that source file was somewhere else, guess in arch/um/kernel,
until 2.6.14, but I think the content was the same).
