I observed below errors in bb overlay install process…

mkdir -p /usr/bin/
cp -v config-pin /usr/bin/
'config-pin' -> '/usr/bin/config-pin'

This actually isn’t a problem with the package, but instead shows a bigger problem… apt/dpkg runs as root, why was it NOT allowed to create a symlink?

Please confirm:

Okay, not sure what triggered it… FileSystem is fine and permission are fine…
