I found another bug in the dhcp generator. Here is the full fix.

We have been waiting for 1.2 to roll for a long time. We have some running in Vyatta (Lenny), some on Vyatta (Squeeze), some on Vyos Hydrogen, and now a summer build from '18, plus RC7 & RC11. Trying to get packages to run the same way across all so change management is consistent has been fun.

since we have the need to add some packages but not upgrade or interfere with what you have done, this does the trick.

we write a lot of packages for ourselves that are in our own repo. we layer them on top of your distro. someone probably issued a global upgrade, rather than for just our stuff.

digging a little deeper, all installations having this issue also have had the package xl2tpd replaced. you ship with 1.3.6+dfsg-2-vyos0. somehow it got replaced with 1.3.8+dfsg-1~bpo8+1

I agree that this should become part of the CLI. The current method is too dangerous and has always been too loose for good syntax checking. It always used to be that you had to use " to embed quotes. That has not worked of late.
