I would suggest contacting the creator of the Gentoo 64 on RPi image. This is a problem with that specific image and works in all other supported distros.
Hi just a quick reply:
Same issue with Fedora 30 (arm64 - RPi3B+) and I assume 31 with the last OS update (kernel 5.5).
Identical error message.
Your fix has worked here too (--priviledged) . Agree about this being somewhat unsafe.
It may be possible to sort through the various --cap-add options to find the right one.
I think Fedora is a "supported distro" so in theory its "just" a matter of the devs loading it up and updating to the latest to reproduce this issue.
I also have the s6 issue where it loops forever (commonly caused by --dns 127.0.0.1 not being present) now.
Pretty sure it was the last OS update that caused these issues (however I only update this machine every couple of months).
BTW I gave up on the Gentoo Sakaki image and went over to the James A Chamber's Ubuntu arm64 image on the RPi4B units - very happy with it.
Replying to my own reply:
I've have to abandon 4.3.2-1_aarch64. It loops forever and won't startup lighttpd. Complete fail now with the latest update of Fedora 30.
4.3.1-4_aarch64 runs OK, but with the --priviledged noted above.
Hope this helps someone as we were down here for while.
for anyone interested in some details, this should be fixing the issue. by the way, none of the --add-cap capabilities help, not even --add-cap=ALL, you really have to stick with privileged mode for now.
EDIT: I'm using pihole on manjaro aarch64
