https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293974 Bug ID: 293974 Summary: [request] [geom_part] gpart(8) should know about iFFS/IRST "Intel Rapid Start Technology" partition type Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: walter.von.entferndt@posteo.net A partition of this type is used to hibernate the machine, i.e. the BIOS transitions the machine from state S3 (suspend to RAM) to S4 (suspend to disk) after a timeout that can be set in the BIOS. It is very useful for laptops or other mobile devices which (occasionally/mostly/always) run on battery. The type id is for MBR: 84h (https://en.wikipedia.org/wiki/Partition_type) and GPT: D3BFE2DE-3DAF-11DF-BA40-E3A556D89593 (https://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs) Search for "Intel" on these pages. It would be great if gpart(8) knows this type by name, so we don't have to type the long cryptic GUID, which is also a source of failure because typically it is done manually on install when no comfortable environment is active (no internet, no copy & paste). I suggest the name "IRST" or "iFFS". The manual page could read: "Intel Rapid Start Technology<TAB>If IRST is enabled in the BIOS, this partition is used to transition from S3 (sleep/suspend to RAM) to S4 (hibernate/suspend to disk). It must be larger or equal to the size of RAM." Maybe the long list of exotic partition types shold be at the end of the manpage in an extra section?
