How to upgrade?
Just a few days ago I installed 1.9.RC3 and I want to upgrade to RC3.1. How to do that? Is my only option to replace the directory with the new version and run the installer again? I tried this already, anyway, and it seems there are distinctive differences between RC3 and RC3.1 regarding permission settings. F.i. many directories now have a sticky bit on the group. Installation of RC3 was a matter of seconds. I ran "setup.sh user group" (with user and group being the user and group of that virtual host in Apache) and was able to continue with setup. If I do the same with RC3.1 the "welcome" message from the installer about lots of non-writable directories doesn't change. Example of differences:
RC3: dir backups: rwxrwsrwx owner group
RC3.1: dir backups: rwxrwsr-x owner group
So, can I rather avoid the clean install for an upgrade or if not: what do I need to do different from RC3?
Thanks.
