I previously had sreadahead 1.0-5 installed. karmic-updates recently supplied
me with
replacements ureadahead 0.90.3-2 and (transitional) sreadahead 1:0.90.3-2.

REPAIR FROM MANUAL REPRO:
r...@goose:~# dpkg --configure sreadahead
Setting up sreadahead (1:0.90.3-2) ...
The sreadahead->ureadahead upgrade appears to have forgotten to remove
sreadahead's registered interest in init files:
r...@goose:~# tail -4 /var/lib/dpkg/triggers/File
/etc/init sreadahead
/etc/init.d sreadahead
/etc/init ureadahead
/etc/init.d ureadahead
This might be purely a local mishap. I had moved back and forth between
old-sreadahead and new-ureadahead while testing their relative
performance, might have messed it up somehow.
Anyway, just adding "triggered" to the list of no-op actions in
sreadahead's postinst script would fix this regardless of how someone
got there:
