Both x11docker and x11docker-gui should be installed to /usr/local/bin to prevent package manager confusion

I have a suggestion which is presented in the title.
It is strange that x11docker installs itself into package-manager-controlled directory - /usr/bin.
Please change the installation folder to /usr/local/bin to ease system administration and to make it more transparent.

I agree that /usr/local/bin fits better for applications that are not installed by a package manager.

The reason why I decided to use /usr/bin instead:
/usr/local/bin is mostly not in PATH of user root and can also miss if using sudo.
But x11docker needs root privileges to run docker if the user is not in group docker.
Adding /user/local/bin to PATH of root is also not recommended.
So x11docker needs to be installed in /usr/bin.

Alternatively, to avoid /usr/bin and /usr/local/bin as well, it could be installed in /opt/x11docker/bin. The user would have to add this path to PATH manually.

A possible solution: x11docker would still install in /usr/bin by default, but optionally allow alternate installation pathes. Option --update should automatically detect and regard the installation location.

Personally I will be very happy with this proposed solution.
On first installation of 6.6.2 I have manually moved x11docker executables to /usr/local/bin, but latest --update to 6.9.0 removed them and installed to /usr/bin instead. So I have manually moved them to /usr/local/bin again. This last step should be automated :)

I've included this in the current beta/master version.
There is still no argument for --install, but --update and --update-master will regard a custom installation path.
I still have to do some adjustments (especially in case of a location in HOME), but for your case it will already work.

However, If you run --update-master now, you'll have to move the files again one time because an older version of x11docker does the update. Same issue will occur if you run --update before a new stable release is published. The current stable release would install to /usr/bin again on next update.

Since v7.6.0 x11docker installs itself into /usr/local by default:
