Hi,
Sorry I wasn't on my pc:
jls@box:~$ grep crda /usr/local/postinst/*
/usr/local/postinst/crda: if [ -e "/etc/udev/rules.d/z60_crda.rules" ]; then
/usr/local/postinst/crda: echo "Preserving user changes to /etc/udev/rules.d/40-crda.rules ..."
/usr/local/postinst/crda: if [ -e "/etc/udev/rules.d/40-crda.rules" ]; then
/usr/local/postinst/crda: mv -f "/etc/udev/rules.d/40-crda.rules" "/etc/udev/rules.d/40-crda.rules.dpkg-new"
/usr/local/postinst/crda: mv -f "/etc/udev/rules.d/z60_crda.rules" "/etc/udev/rules.d/40-crda.rules"
