I'm applying changes to the packages. This is my vdev.conf file:

________    *vdev.conf*    _________

[vdev-config]
firmware=/usr/lib/firmware
acls=/etc/vdev/acls
actions=/etc/vdev/actions
helpers=/usr/lib/vdev
hwdb=/usr/lib/vdev/hwdb/hwdb.squashfs
ifnames=/etc/vdev/ifnames.conf
pidfile=/run/vdev/vdevd.pid
default_permissions=0600
loglevel=debug
logfile=/var/log/vdev/vdevd.log
preseed=/usr/lib/vdev/dev-setup.sh



I also added the following files:

________    *vdevd.postinst*    _________

I also added a *vdevd.postint* file:

#!/bin/sh

set -e

ln -s /usr/sbin/vdevd /sbin/vdevd

#DEBHELPER#

________    *vdev-example.postinst*    _________

#!/bin/sh

set -e

PREFIX=/

if [ $# -gt 1 ]; then
    PREFIX=$1
    shift 1
fi

update-rc.d -f udev remove
update-rc.d -f udev-finish remove

ln -s /usr/etc/init.d/vdev /etc/init.d/vdev
ln -s /usr/etc/vdev /etc/vdev
update-rc.d -f vdev defaults
insserv

cd /etc/rcS.d
rm S03udev S10udev-finish
ln -s ../init.d/vdev K02vdev
update-rc.d vdev enable S

mkdir /etc/vdev/acls
echo \
"[vdev-acl]
uid=0" > "/etc/vdev/acls/00-whitelist-root.acl"

update-rc.d -f udev remove
update-rc.d -f udev-finish remove
update-rc.d -f vdev defaults
insserv

#DEBHELPER#

________    *vdevfs.postinst*    _________

#!/bin/sh

set -e

ln -s /usr/sbin/vdevfs /sbin/vdevfs

#DEBHELPER#

________    *vdev-fs.postinst*    _________

#!/bin/sh

set -e

ln -s /usr/sbin/vdevfs /sbin/vdevfs

#DEBHELPER#



I also have to add the *.postrm files.

Cheers,

Aitor.
