I'm running 2.4.2ac7, and am having problems with Unix98 ptys. Occasionally rxvt and Eterm fail to run because they can't get permission to create their entry in /dev/pts. So i wondered if i have a devfs problem, which led me to the following...
In Documentation/filesystems/devfs/README, it is thus written:
Disable devpts I've had a report of devpts mounted on /dev/pts not working correctly. Since devfs will also manage /dev/pts, there is no need to mount devpts as well. You should either edit your /etc/fstab so devpts is not mounted, or disable devfs from your kernel configuration.
i don't have devpts mounted under 2.4.2 (debian checks whether you have devfs before mounting devpts), so i tried building my kernel with Unix 98 pty support but without the devpts filesystem. i get the following error at the very end of 'make bzImage':
drivers/char/char.o: In function `pty_close': drivers/char/char.o(.text+0x6646): undefined reference to `devpts_pty_kill' make: *** [vmlinux] Error 1
so the devfs documentation is wrong; pty_close depends on functionality from devpts. and secondly, has anyone else had problems under 2.4.x creating entries in /dev/pts?
