I did:
#!/bin/bash -e
set -x

I figured it would essentially be the same...

Now the tests repeated, with:

root at neminis:~# head -n2 /var/lib/dpkg/info/grub-pc.postinst
#!/bin/bash -ex
#set -x
root at neminis:~# DEBCONF_DEBUG=developer dpkg --configure -a

Repeating only the postinst command gives the following:

128

I double checked, but /boot/grub/menu.lst was not modified (it should,
right?)
