[Bug 1643063] Re: unable to ifup vlan based interface with systemd persistent naming

[Kevin Otte]

This may need to be filed against the vlan package as /etc/network/if-pre-up.d/vlan is owned by same.
It was my understanding, however, that vconfig was deprecated in favor of 'ip link' as used in my workaround.
