You shouldn't need pt_chown; devpts just needs to be mounted correctly. > Instead I found that changing the gid of group tty to 5 fixed konsole > (the tty group had a gid of 4 on my system). That's old, see below. On the other hand, I have gid=N in my fstab, with N an integer, not a name.

The book assigns gid 5 to tty: http://www.linuxfromscratch.org/lfs/view/development/chapter06/createfiles.html ...per Bruce's comment that "we changed that to 5 quite a while ago" in the discussion of changing the chapter-6 devpts mount (http://www.linuxfromscratch.org/lfs/view/development/chapter06/kernfs.html) to provide -o gid=5 to get the glibc testsuite to work. (I'd point to the archives, but it seems they're 404, probably due to the server move. I'm pretty sure it was less than a week ago though.) See also: http://www.linuxfromscratch.org/lfs/view/development/chapter08/fstab.html where it's numeric, and 5. > I suggest we add the tty group with gid 5 to the "About System Users > and Groups" in BLFS and maybe also add a note to the konsole page. Not going to be just konsole; it'll affect any program that tries to grantpt() as part of the PTY allocation handshake. xterm, aterm, sshd, expect, you name it.
