It is very useful for laptops= or other mobile devices which (occasionally/mostly/always) run on battery. The type id is for=20 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 TechnologyIf 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 large= r or equal to the size of RAM." Maybe the long list of exotic partition types s= hold be at the end of the manpage in an extra section?
