Package: debconf
Version: 1.4.30.13
Severity: normal
Hello,
/bin/sh on this system is dash, which shows this behavior:
----------
foo='\\Nblah' ; echo "$foo
\Nblah
----------
Please note the missing second backslash.
/usr/share/debconf/confmodule uses "echo" to pass values to debconf,
mangling \\ by this. I've stumbled upon this in exim4, with this code
used for debugging:
printf '%s\n' "Original ${dc_other_hostnames}" | logger
db_set exim4/dc_other_hostnames "${dc_other_hostnames}"
db_get exim4/dc_other_hostnames
printf '%s\n' "Debconf-db ${RET}" | logger
This results in this output in syslog:
Apr 24 14:38:58 argenau logger: Original downhill.aus.cc:\\Nbar\\N
Apr 24 14:38:58 argenau logger: Debconf-db downhill.aus.cc:\Nbar\N
To test my guesswork I verified that this crude change indeed fixed
the problem:

# Commands.
_db_cmd () {
- echo "$@" >&3
+ /bin/echo "$@" >&3
I _think_ the correct way to fix this is:
- echo "$@" >&3
+ printf '%s\n' "$*" >&3
thanks, cu andreas
PS: Thanks to Sam Hocevar and Lars Wirzenius for helping me on IRC
with this.
