There error is hard to trigger. It has occurred 26 times within the last 49
days (check interval 15 min)

No, there is no logging to the tty. I don't know ulogin exactly. Just changed
some values at sleep (see ulogin.patch). It's rancid version 3.6.2

For two devices I just created a rancid.types.conf

terminal length 0 is working. I'm unsure if setting "| no-more" really helps.
Have a look at attached log. Devices ams-gw and kleyer90-gw are type
edgerouter and those with IPs are edgerouter_custom.

diff_withedgerouter shows the problem with the standard edgerouter type.
