As far as I know / recall this is suspend-to-ram behaviour, suspend-to-disk must go through the normal hardware initialisation (BIOS or whatever is the equivalent on the given platform) because the system is powered off. > Hence, is the chance that the > "wrong" sytstem is resumed (causing all kinds of havoc) so high actually?

It's safe to use only if the user never suspends to disk, or takes care to always choose the suspended installation at boot. > * If the user selects the existing partition (i.e. not created in this > installer session) for "use as: swap", then the installer gives a dialog > with this text (or similar in better English...): > > | You have selected a previously existent swap partition to be used for > | swap. > | > | While this is tecnically possible without reformatting, sharing swap > | between multiple Linux installations (Debian or not) is explicitly > | advised against (see <<<URL>>> for details).
