vrx_entrypoint.sh does not expand "~" to correct user home directory

This is a problem with the Dockerfile, build and run scripts. They use a hardcoded value of 1000 for the UID and GID when building the container, but then dynamically run with UID and GID that match the local user. So, if the user's UID and GID are not 1000, the system fails to set up the user environment correctly and can't find $HOME.

Unfortunately, fixing this produces a pathological behavior when running the adduser command, causing the build process to hang at Copying files from /etc/skel. There are several possible reasons for this, but the one that seems to fit best in this case is that the filesystem doesn't support sparse files and therefore is failing while try to copy lastlog. This is a sparse file that will appear especially big when it has to handle large userids, which is the case on my system. As a result the build process remains stuck until my partition runs out of space. See here for a similar report.

The fix should be to use a --no-log-init option. But Ubuntu's version of adduser doesn't support this option, so we have to switch to useradd.

@caguero I now have this fixed locally. When I get write access to the repository I will submit a PR.
