It seems, even though we are writing 2019 on the calendar, that IPv6 is still not fully supported.
I have recently tried the VCSA backup feature on a number of VCSAs and they all fail consequently at about 35%. When I look in the backup.log, I find an error like this:
BackupManager encountered an exception: While reading from '/etc/systemd/network/10-eth0.network' [line 7]: option 'gateway' in section 'Network' already exists
The 10-eth0.network file looks like this:
[Match]
Name=eth0
[Network]
Gateway=2001:****:248:64::100:1
Gateway=172.**.100.1
Address=2001:****:248:64::100:203/64
Address=172.**.100.203/23
IPv6AcceptRouterAdvertisements=false
DHCP=no
[DHCP]
UseDNS=false
Which is a perfectly legal dual-stack config file.
All our VCSAs are running 6.7U2 (6.7.0.30000)
