This is my feedback comparing dietpi and Pi OS lite. This is also my first contribution to this forum.
I wanted to have alternative system for my pihole on pi zero w. I have exactly zero experience with dietpi.
Installation: Documentation to install is not great. I was looking for instruction how to DD or copy provided image to sd card, never found one, so I simply tried. I was looking for making a wpa_supplicant, because, remember, it is pi zero w, no keyboard, no monitor, no nothing. I figured out that wifi is set in some alternative place. ssh is enabled by default, nice.
First boot. This was painful, interactive guide was insisting on testing DNS resolv, but probably under ipv6. It keeps failing.
When I force it, using ping to 18.104.22.168 or something along those lines, it works, sort of.
System then self updates, without asking me about it. At least it did not failed. Pi OS lite fails on apt-get upgrade when deploying new firmware and kernel…bricking device like pi zero w.
When I try to install anything, say pihole or nmap, it start nagging with testing my DNS, using hardcoded quad servers. My DNS is just fine, why it keeps nagging? I run alternative command ‘true’ but why it does not offer ignore option?
At the end of day, I gave up (for now), I do not know if I have or have not ipv6 address and/or connectivity on this device, or if there is some problem. Why is that important enough to keep nagging about it every 30 seconds?
What it can and can not do? How do I install software withhout that dns nagging propmpt? What was my ip, both v6 and v4? is zeroconf running? mDNS?
WHAT I LIKE: less writing, by default. SD should work longer.
