That's not right. :-) What happens if you try to ls -l the new slave char device? ls -l /dev/pts (ls -l /dev/pts) </dev/ptmx The latter should show one more device than the former; the owner, group, and permissions on that should be you, tty, and 0620, otherwise (IIRC) pt_chown is necessary. (I should probably go dig through the glibc sources for grantpt() to find out for sure though.) ...Wait, this might be the issue. chapter06/kernfs.html says: mount -vt devpts devpts $LFS/dev/pts but my fstab has: devpts /dev/pts devpts gid=4,mode=620 0 0 The mount probably needs -o gid=4,mode=620 added. If you add that, do both the tests start working? ...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.
