Since you decided to put it in /sbin which isn't and shouldn't be in normal user path, it should be only run as root because of that. On the other hand, I can perfectly run it as normal user. It might just print a warning though, it isn't anything critical if it can't open /dev/kmem. That shouldn't be something user should be able to read anyways. -- Note: My last name is not Krejzi. -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
