If I change SELinux from disabled to enabled (or permissive first) will it take long to rebuild the SEL labels on about 250GB file system?

I’m just learning about SEL at the moment, so I want this to be done correctly by the system itself.
It would be ‘awsome’ if you lost all those SIGs please. It gets annoying and makes me not want to answer any your questions.
You can’t go wrong with this , . Dan Walsh has the most up2date info on SELinux (rhel maintainer)

Thanks for those pointers.
I’m working my way through  now, which I downloaded a few days ago.
