[PVE-User] vzifup-post errors

[Derek W. Poon]

When I run /sbin/ifup vmbr1, the following error appears:
 Usage: vzarp-ifup DEVICE
 run-parts: /etc/network/if-up.d/vzifup-post exited with return code 1

# dpkg -l vzctl

ii  vzctl          3.0.23-1pve8   OpenVZ - server virtualization solution


According to interfaces(5), the interface name is passed to post-up scripts via the $IFACE environment variable, not via a command-line argument.  The following patch fixes that, as well as a syntax error with a -z test.
