Problem Description
While I set off the entirety of Tuesday on doing one proper setup of Fedora Workstation 34 aarch64, I had far more problems getting systemctl to recognise AGH on Fedora boot, than on any other distro I had tried.
After some 5 hours did I come across #765 (comment), but I had to do one additional thing to fix the problem on my end:
It turns out that SELinux is extremely overzealous in its firewall protection and its anti-/home/ behaviour. It's not merely enough to copy an existing installation from /home/username/Documents to /usr/local/bin and reinstall the service from there. AGH's initial setup must've occured from a clean slate in /usr/local/bin, which finally seems to have made AGH start as a service on boot.
This allowed me to avoid the dreaded (and honestly bewilderingly non-verbose) "203 exited-code" status, so I can only presume that it's nice info to add to the FAQ and to the Fedora section's title.
Proposed Solution
In the wiki pages, add info on SELinux and various causes of status '203 / exited-code' in Fedora, and to add them more prominently if possible. Probably also add info in "Getting Started" on that AGH is completely unable to run as a service from /home/ on distros that use SELinux.
Alternatives Considered
None that I can't think of.
Additional Information
I know I did a lot to try to fix the problem, including forking=1; setting AdGuardHome/data to be writeable by all users (In one instance I failed to reproduce later on, the data folder was write-protected for non-root users); and extending StartLimitInterval and StartLimitBurst in /etc/systemd/system/AdGuardHome.service to 15 and 30 respectively.
