Bug#588915: postinst: /usr/sbin/update-initramfs: line 199: do_b: unbound variable

[Ben Harris <bjh21@cam.ac.uk>]

Package: initramfs-tools
Version: 0.97.2

When configuring initramfs-tools, this happens:

wraith:~# dpkg --configure initramfs-tools
Setting up initramfs-tools (0.97.2) ...
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools ...
update-initramfs: Generating /boot/initrd.img-2.6.32-5-686
/usr/sbin/update-initramfs: line 199: do_b: unbound variable
dpkg: error processing initramfs-tools (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 initramfs-tools

Until recently, this system has been running locally-compiled kernels.  I 
recently installed a packaged kernel, linux-image-2.6.32-5-686 version 
2.6.32-15, and this pulled in initramfs-tools for the first time, which 
failed on configuration.

I suspect there's _something_ unusual about my system that causes this 
problem, but better reporting of what it is would be nice.
