My soon-to-be web hotel uses PHP in safe mode. Is that a problem when running drupal 6.x?
What works and what does not work?

It is generally not recommended to run Drupal in a environment with safe mode on. You can read more about safe mode at http://us3.php.net/manual/en/features.safe-mode.php, note the link toward the top listing functions that are disabled.

In general file related functions are disabled so upload images/files as well a connections to other sites generally will not work. Also certain functions are disabled that will break certain functionality.

Safe Mode is deprecated in PHP 5.3.0 and is removed in PHP 6.0.0.
