cat 9feac7738f internal/pkg: optionally suppress via assumed checksum 
This is quite error-prone and causes cache inconsistency similar to the store inconsistency seen on nix when a similar condition happens. Keep this behind a flag in case it is ever beneficial.

cat a6600be34a all: use filepath 
This makes package check portable, and removes nonportable behaviour from package pkg, pipewire, and system. All other packages remain nonportable due to their nature. No latency increase was observed due to this change on amd64 and arm64 linux.
