[Bug 1309788] [NEW] ifup does not execute if-up.d scripts for manual interfaces

[Theo Cabrerizo Diem]

Public bug reported:

When having an interfaces stanza:

auto myvpn
iface myvpn inet manual
    openvpn myvpn

At least on ubuntu 13.10 (confirmed with ifupdown  0.7.44ubuntu3), doing a 'ifup -v myvpn' resulted in:
# ifup -v myvpn
Configuring interface myvpn=myvpn (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/ethtool
run-parts --verbose /etc/network/if-up.d
run-parts: executing /etc/network/if-up.d/000resolvconf
run-parts: executing /etc/network/if-up.d/ethtool
run-parts: executing /etc/network/if-up.d/ntpdate
run-parts: executing /etc/network/if-up.d/openssh-server
run-parts: executing /etc/network/if-up.d/openvpn
 * Starting virtual private network daemon(s)...
 *   Starting VPN 'myvpn'
run-parts: executing /etc/network/if-up.d/upstart
#

On ifupdown 0.7.47.2ubuntu4 (trusty):
# ifup -v myvpn
Configuring interface myvpn=myvpn (inet)
run-parts --verbose /etc/network/if-pre-up.d
run-parts: executing /etc/network/if-pre-up.d/ethtool
ip link set dev myvpn   up
Cannot find device "myvpn"
Failed to bring up myvpn.
#

IMHO the mentioned line (ip link set ...) seems to be called before the
if-up.d/* scripts. I cannot confirm if the origin of the issue is the
same change mentioned in the bug #1305271, since I don't have the tools
to rebuild the package without the mentioned line.
