I'll try again: Maybe I shouldn't try to guess Peters meaning, but maybe he was trying to think out an implementation of pm-is-supported. Indeed how thorough should this check of `is supported' be, is an interesting question. Really suspending devices and trying to write to swap for hibernate for example seems a bit overkill to me... But checking if the configured swap partition / file exist seems sane. For uswsusp checking if the device node which is used for communication with kernel is available is another. For the rest I think we can assume things will work. grts Tim _______________________________________________ Pm-utils mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pm-utils
