ENOENT (No such file or directory)

(Permission denied)

such file or directory)

close(1)                                = 0
close(2)                                = 0
exit_group(126)                         = ?


/root/bin/ directory is not created in koji buildroot (it is not created by 
default at all) - so that might be the difference.
