My only hickup is SElinux, otherwise the permission system on linux is annoying but admin friendly minus stuff like /dev/mem always being denied and libfuse understanding and miscommunicating the risks of the “allow users (with correct permissions) to access another user’s fuse partition” setting. (And its not user privicy, its DOS prevention)
tbf /dev/mem is mapped to physical memory, access to most of which is completely denied by the memory controller in the cpu (while it’s in usermode), no matter rhe access level
