    /dev/shm wasnt mounted, but i created the mount-point, & added the following
    to /etc/fstab:

    none /dev/shm shm defaults 0 0

    & re-booted. (sysvipc is compiled into my kernel..)

    lp still complains "no devices found"

    the only other thing i havent mentioned (will it make a difference?) is that
    i'm running reiserfs.

    [root@ansonic /root]# mount
    /dev/hda2 on / type reiserfs (rw)
    none on /proc type proc (rw)
    /dev/hda1 on /boot type ext2 (rw)
    /dev/hdb1 on /home type reiserfs (rw)
    none on /dev/pts type devpts (rw,gid=5,mode=620)
    none on /dev/shm type shm (rw)
    [root@ansonic /root]#

    cheers :)
