I have just upgraded to v9.3 by doing a new installation and am have a question about permissions. I have an application, Tinder, that has a default installation directory of /opt for the file tree and the need to install symlinks in /usr/local/bin. Naturally, all of these directories are root/root. I want to run the installer as a user, not as root. I have one user on the system, computation which belongs to th dialout, video and users group. So I need to know how to set the permissions so that I can install, and run, tinker as the user computation. Another problem, about which I have no clue, is that i get a message from the installer: 'install4j An error occurred: java.io.IOException: Too many open files Error log: /tm//install4jError19740log' This causes the installer to bomb at about 70% completion (I tried running the installer as root one time, although I wasn't happy doing that).
