Ubuntu/Linux setup instructions

[aj-may]

On some Ubuntu/Linux distros, there is an internal DNS server run by the system and usually /etc/resolv.conf is overwritten by other network management software.

It would be nice to have some docs in the README that outlined some simple steps to follow on those distros to set the network settings so they don't conflict with this tool.

Some things may be able to be automated as part of the Setup DNS step in dotdocker.

do you have a recommendation here? this seems to have removed my DNS settings at /etc/resolve.conf

sudo dotdocker start
  ✔ Start dotdocker containers
  ✖ Setting up DNS
    → ENOENT: no such file or directory, open '/etc/resolv.conf'
