Package: udev
Version: 0.070-5
Severity: critical
Tags: patch
Justification: breaks unrelated software
The dvb.sh script was replaced with inline code in udev 0.070-1. This
code fails to produce /dev/dvb/* nodes: following errors were seen.
Oct 16 12:29:47 localhost udev[7381]: udev_make_node:
mknod(/dev/dvb/adapter/, 020660, 212, 4) failed with error 'File exists'
Oct 16 12:29:47 localhost udev[7385]: udev_make_node:
mknod(/dev/dvb/adapter/, 020660, 212, 5) failed with error 'File exists'
Oct 16 12:29:47 localhost udev[7392]: udev_make_node:
mknod(/dev/dvb/adapter/, 020660, 212, 7) failed with error 'File exists'

On my system, /bin/sh was symlinked to dash.
lrwxrwxrwx 1 root root 4 Aug 29 2004 /bin/sh -> dash
Replacing this with a symlink to bash fixes the inline dvb code.

The problematic line is in udev.rules
KERNEL=="dvb*", PROGRAM="/bin/sh -c 'K=%k K=$${K#dvb} \
A=$${K%%%%.*} D=$${K#*.}; echo dvb/adapter$$A/$$D'", \
NAME="%c"
There's a deficiency in dash, as demonstrated here.
$ /bin/dash -c 'K=dvb0.net0 K=${K#dvb} ; echo $K'
<empty line>
$ /bin/bash -c 'K=dvb0.net0 K=${K#dvb} ; echo $K'
0.net0
$ /bin/dash -c 'K=dvb0.net0 ; K=${K#dvb} ; echo $K'
0.net0
I recommend changing the "PROGRAM" to explicitly use /bin/bash, or to
use the variant with extra semicolons as a workaround for dash.
I've also lodged a bug with the dash package.
