Look to other orchestrations solution too, like SALT. If you need to manage a lot of servers it is live saver. Setting up is only first step.

Usually just plug/unplug couple of times is enough. No fancy chemicals.
Run long smart test on the disk and check smart data after that. Other possibility is ZFS pool is nearly full.
Depends what are you doing. Something like keep base os patched is pretty much nil efforts. Some apps more problematic than others. Home Assistant is always a pain to upgrade and something like postfix is requires nearly 0 maintenance.
circular dependency seems to be the case. I guess adding second external resolver to /etc/resolve.conf will help. Second entry will not be used unless first one ( pi-hole) is responding. But it need to be tested.
BTW, why do you want to send host's DNS via pihole?
what exactly do you mena under subdomains?
Any DNS provider will support adding NS entries for subdomains if you want to host you sub-zone somwhere, And any should allow you to use names with "." in it for "fake" subzone, like
a.subzone1 IN A x.x.x.x
a.subzone2 IN A y.y.y.y
nope, it is very deeply customized debian. Need to be installed from scratch.
Open source projects need to make money somehow. I found VyOS method quite acceptable. They giving good instruction and tools to build your own stable ISO. So do not be lazy or contribute somehow. Unfortunately their paid support costs too much. I was considering trying to push VyOS to be used as virtual router at my work, but it costs more than Cisco C8000v
Try VyOS. I run it on APU2 myself. No GUI no convolution.
Very strange line from specs.

Does it mean binary blob driver only? and you need to pay for it to use it on PC?
If you still use HTTP for cert verification on ACME, you are doing it wrong. Use DNS-01 only, there is no need to allow any inbound traffic to your servers. and HTTP will not give you wildcard anyway.
