@thinkl33t, recommended way is using dynamic-dns-update, all other ways are not recommended to use at this moment.

Yeah, I'd mark this not-a-bug. Update the documentation to mention hosts file update with failover doesn't maintain consistent state between failover servers.

thinkl33t added a comment to T1076: SSH: make configuration (sshd_config) volatile and store it to /run.

Could we work around this by implementing an overlay for every commit, with the entire stack of overlays being combined with the root overlay when a save is issued?

I've finally managed to test this (apologies, we've had a super busy couple of months) and don't appear to be able to connect to the VPN anymore :(

I've put in the suggested kernel parameters for my install to disable the broken functionality. Hopefully this will keep it stable until a version with an upgraded kernel is available :)

Note that this has taken down DNS on our firewall (and hence our network) a couple of times now, both annoyingly early in the morning when nobody was in to fix it.

thinkl33t added a comment to T659: Static DHCP mappings aren't available on DNS.

I've implemented this in our ansible-derived vyos configuration by allowing the static addresses to be generated with the VLAN prepended and adding a system static-host-mapping for the fqdn to ip.

I've done a bit of fiddling with this today on a test VyOS 1.2.0-rc6, Attempting to set a custom option and pass it through to the leases file. Unfortunately I wasn't successful.
