Ubunutu 19.10 (setsid not found)

[Henning Reich]

Hi,
maybe someone can help for a "elegant" solution ;-)

I'm trying to get an unattended boot of a fresh installed Ubuntu 19.10.
The basic setup works. I mean:

/usr/lib/x86_64-linux-gnu/mandos/plugins.d/mandos-client
--pubkey=/etc/keys/mandos/pubkey.txt
--seckey=/etc/keys/mandos/seckey.txt -t
/etc/keys/mandos/tls-privkey.pem -T /etc/keys/mandos/tls-pubkey.pem
--connect=10.0.0.173:9601;echo
returns my test password.

But if I boot it, I got an error:
/scripts/init-premount/mandos: line 180: setsid: not found

Quick & Dirty solution is to remove "setsid" from the mandos script,
but I think there was/is a reason setsid is used. Maybe I have to add
setsid manual to the initramfs? But how? Or how did you solve this
issue? Or does nobody use  a (non LTS) ubuntu?

Thanks and have a nice 2020
