I want to build a test system based on OpenBSD 5.7 which updates
in an automated fashion.
The goal is to have a remotely located machine which runs OpenBSD 5.7
and is constantly updated. While restarting the machine remotely via
SSH
is perfectly fine to me, I do not want to access the machine locally in
order to interrupt the automatic reboot in order to trigger the manual
upgrading process. I'm fine with following -stable and -current alike.
I recognize that there's m:tier's binary patching service
(https://stable.mtier.org), but the packages are signed
by m:tier rather than the OpenBSD project. While following m:tier's
binary patches is a good compromise to me, it's not a perfect solution.
I'm perfectly fine with running the -current flavour of OpenBSD
feature-
and stability-wise, but I did not have the success of remotely
triggering
a script, rebooting the machine and have an up and running updated
machine.
While I did find the autoinstall(8) feature, which, since 5.7, should
be
able to trigger an automatic upgrade if the file /auto_upgrade.conf is
present, I did not see an effect in the bootup messages on the virtual
machine I'm using for testing things out.
Furthermore, I did find a tool named snap, aiming at making running
-current more enjoyable (see https://github.com/qbit/snap), but it does
also seem to be relying on the user to manually start the upgrading
process on system reboot, if I got everything correctly.
Is there someone aware of a procedure which could help me solving my
problem?
I thank you very much in advance.
Peter
Hi,
autoinstall(8) is your friend:
