Can you mount SMB shares in unprivliged containers? I thought that was blocked.

Can the host itself write to the file share? You can check this by trying to create a file in it via the host’s shell. If it can’t write to it the container won’t be able to either.

What was this guy doing to break his pihole all the time? I can’t remember the last time I logged into mine at all.

Microsoft is a lot more aggressive with EoLing it’s Windows versions now exactly because XP lived so long. It was an absolute pain for them to maintain and support that for so long and they’ve made very sure they don’t repeat that experience.
