If the context for /var/opt/quest/vas/vasd(/.*)? all files

Is already in place before the product is installed via rpm, should
rpm correctly label the dir/files as they are laid down?
The point is the directory
needs to be a part of rpm payload.
# rpm -qf /var/opt/quest/vas/vas
Otherwise you need to run restorecon to fix labeling.

Pid files are created by the app, and the app does not look at the file
context. file_context is just there to tell SELinux aware apps how to
label
content. (restorecon,rpm) If non SELinux aware apps create content
then you
need file transition rules.
