rancid 3.x - juniper display set

I found a lot of directions on the net for how to change rancid 2.x to do "display set" for juniper switches, but none for rancid 3.x (this was tested on rancid 3.1.2 on CentOS 6.6)

It's actually pretty easy:
  1. Find your switch type (in this case "juniper") in /etc/rancid/rancid.types.base and copy those lines into /etc/rancid/rancid.types.conf:

    juniper;script;rancid -t juniper
    juniper;command;junos::ShowConfiguration;show configuration

  2. Now change "juniper" to some unique string that doesn't exist in rancid.types.base, e.g. "juniper-dset"
  3. Modify all the "juniper" strings in rancid.types.conf to be "juniper-dset"

    juniper-dset;script;rancid -t juniper-dset
    juniper-dset;command;junos::ShowConfiguration;show configuration

  4. Add a new line to do the display set:

    juniper-dset;command;junos::ShowConfiguration;show configuration | display set | no-more

    It's up to you whether you want that before or after the normal multi-line "show configuration".

  5. Also, change /var/rancid/router.db to change the "juniper" switch type to "juniper-dset"
