You really need to keep up to date a little more. We changed tty to gid 5 quite a while ago (April 2012). In any case, remounting /dev/pts with the proper options did work for ./testpt. Rerunning the util-linux tests with the /dev/pts mounted with the proper options did indeed allow the non-root tests to pass. > ...And now that I say that, I think I have a change hanging around in my > local svn repo that I never submitted, that adds this to this chapter 6 > mount command. If it fixes this, I should probably submit it. I'll go ahead and make the change to the book. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
