| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Caveats: The new savecore program is not complete in the sense that it emulates enough of the old savecores features to do the job, but implements none of the options yet. I would appreciate if a userland hacker could help me out getting savecore to do what we want it to do from a users point of view, compression, email-notification, space reservation etc etc. (send me email if you are interested). Currently, savecore will scan all devices marked as "swap" or "dump" in /etc/fstab _or_ any devices specified on the command-line. All architectures but i386 lack an implementation of dumpsys(), but looking at the i386 version it should be trivial for anybody familiar with the platform(s) to provide this function. Documentation is quite sparse at this time, more to come. Sponsored by: DARPA, NAI Labs Details: Dumpon now opens the device and uses ioctl(DIOCGKERNELDUMP) to set it to be the dumpdevice. When "off" is set, /dev/null is used.
