In case another ignorant fool like me runs in to this error. I found the
solution in the kernel config help for sysv-ipc, I just needed to realise it
was related to IPC!! The magic fix is just adding the corrwect line to
/etc/fstab.
System V IPC
CONFIG_SYSVIPC
Inter Process Communication is a suite of library functions and
system calls which let processes (running programs) synchronize and
exchange information. It is generally considered to be a good thing,
and some programs won't run unless you say Y here. In particular, if
you want to run the DOS emulator dosemu under Linux (read the
DOSEMU-HOWTO, available from
http://www.linuxdoc.org/docs.html#howto ), you'll need to say Y
here.
You can find documentation about IPC with "info ipc" and also in
section 6.4 of the Linux Programmer's Guide, available from
http://www.linuxdoc.org/docs.html#guide .
Shared memory is now implemented using a new (minimal) virtual file
system, which you need to mount before programs can use shared memory.
To do this automatically at system startup just add the following line
to your /etc/fstab:
none /var/shm shm defaults 0 0
Saying Y here enlarges your kernel by about 18 KB. Just say Y.
Cheers all,
Matt
