[one-users] wrong restart -> delete disk image!

[samuel]

Thank you very much!

Is it safe to manually change the code and just perform a ./install.sh from
the sources on a running installation? I'm using Mysql backend so I expect
that the modification of the sources will only affect the compillation of
the modified library and the rest will continue working ok.

Am I right?

I really appreciate the fast response.
