grml 2008.11 rc2 (i386) booted from USB media, created with grml2usb (from git,
e5d76fc36d463a20a00153d39e6e9767329718c3).

When running `grml-terminalserver-config initrd`, the following message gets
printed, before the expected messages:
---
dirname: missing operand
Try `dirname --help` for more information.
---

I believe this happens because the invocation of find(1) in the assignment to
MULTIBOOT_PATH_ in /usr/share/grml-terminalserver/default_config generates an
empty result list; because it looks for linux26 in /live/image/boot, but on
grml2usb media linux26 is in /live/image.
