Edgar, this is very interesting! Great work! A quick question, did you also deploy the metrics dashboard on Heroku?
Thank you very much Sanjiva!! Thanks for pointing that error!!
Yes exactly, chroot has been introduced in Version 7 Unix (according to Wikipedia) and it has been done by Bell Laboratories. Later in 1982 chroot has been added to BSD. Yes AT&T has also worked on Unix in early 1980s on commercializing it, so it should have been included in that too.
