[K12OSN] Sharing a life-saving command

["Alan Hodson" <aahodson episd org>]

Hi folks

After a K12LTSP 4.2 yum update, and some minor tweaks, one of the
servers that is heavily used at a middle school I work with
(keyboarding) started behaving very strangly giving me on reboot
'portmap errors while loading shared libraries' leading to more
permission denied errors, nfs quota errors, and many more!

Long story short - as root I was able to execute 

restorecon -R /

and while it took quite a while, the next reboot came up roses. Perhaps
some of our gurus can explain what this command does - all I know is
today it was a life saver for me, and I wanted to share it with the
group.

Cheers
