#3268: GNU Screen pty group
--------------------+-------------------------------------------------------
Reporter: stu | Owner: blfs-book@…
Type: defect | Status: new
Priority: normal | Milestone: 6.7
Component: BOOK | Version: SVN

--------------------+-------------------------------------------------------
Section 6.6 of the LFS book sets up /etc/group so that tty is gid 4 and
tape is gid 5. The GNU Screen source code assumes tty will have gid 5.
PTYs created by screen sessions will thus end up with a group of "tape"
instead of "tty"--which will manifest itself in subtle ways (like the mesg
command from util-linux refusing the change permissions).
The best fix is obviously to update screen's logic to use getpwnam, but
short of that this issue can be fixed by adding "--with-pty-group=4" to
screen's configure step.
