That's true, but SYS.COM is needed for installing boot sectors (built-in to SYS.COM and modified on use) as well as configuring a few minor options for the kernel (see "SYS CONFIG /HELP"). Without "BOOTONLY", it will try copying KERNEL.SYS and COMMAND.COM from either the current dir (or if not found, root dir) to the destination. And "FORMAT /S" needs SYS.COM to exist in order to call it.

P.S. If you want to know what FATs your current kernel supports (up to FAT16 or up to FAT32), in case you're curious or forget or whatever, you can always use Eric's WHICHFAT. (A FAT16-only kernel saves a few Kb of space.)
