Good one :)

Seems like there a probleme here(L7 to L9) a got a "* deploy user already exists" message. Fix it by removing &> /dev/null

@vijayn Thanks

@nicolas-besnard If deploy user does not exists it "id -u deploy &> /dev/null" returns 1, it returns 0 if the user exists, have you ran the script two times or do u have the user already ?

@42races Excellent! Excuse my ignorance, does this script generate a deploy user who is not practically capable of running anything with sudo? I tried sudo apt-get update and I get a prompt for a password which was never set. Is that by design or am I missing s'thing obvious?
Thanks
