I understand why I can't set different types for files below /proc/
(because they are virtual and have no inode).
/proc/ is a directory with an inode on my hd, so I should be able to set a
rc type (and the type should be remembered after reboots because the
inode doesn't change) ?
Every file below /proc/ gets the default 'inherit parent dir' and should
get the type of /proc/ because of that?

What's the solution for that problem? I use devfs so it's the same for
/dev/. Do I have to leave /proc and /dev with rc type 'inherit parent dir'
? So if a role wants to read in /proc I always have to give read access to
/, /proc and /dev ?

Thanks for your help!
