Bug#591909: please include init.d script for zvol

[Henrik Riomar <henrik.riomar@gmail.com>]

Package: zfsutils
Version: 8.1-2
Severity: wishlist

The zfsutils package is missing a init.d script for zvol, making the
zvol:s inaccessible after reboot;

# ls -ld /dev/zvol
ls: cannot access /dev/zvol: No such file or directory

# zfs volinit

# ls -ld /dev/zvol
dr-xr-xr-x 3 root root 512 Aug  6 14:36 /dev/zvol

# mount /dev/zvol/tank/ufs-test /mnt/

# df -h /mnt/
Filesystem            Size  Used Avail Use% Mounted on
/dev/zvol/tank/ufs-test
                       49M  4.0K   45M   1% /mnt

# mount | grep mnt
/dev/zvol/tank/ufs-test on /mnt (ufs, local)

In Freebsd this is handled by the rc.d script called zvol;
http://svn.freebsd.org/viewvc/base/release/8.1.0/etc/rc.d/zvol?revision=210188&view=markup

Please include a similar init.d script in Debian GNU/kFreeBSD
