In a previous post I wrote about the possibility to develop PHP applications using a tablet. The main trouble was to find a reliable application to run a web server with a recent version of PHP featuring xDebug and the ability to run unit tests. It's manageable but not fully satisfying so I kept looking for another solution.
Then I found GNURoot Debian and it changed everything : Debian Jessie running inside a virtual machine, you can't ask for more.
I tried several Linux emulators and GNURoot Debian was the only one to work easily without tweaking its configuration. For instance, LinuxDeploy seems very powerful but it never managed to write its configuration on the file system. Even the higher level of logging didn't point out what the real problem was.
