**Note:** _`$BOOT` should be considered **shared** among all OS installations of a system. Instead of maintaining one `$BOOT` per installed OS (as `/boot` was traditionally handled), all installed OS share the same place to drop in their boot-time configuration._
`$BOOT` must be a VFAT (16 or 32) file system. Other file system types should not be used. Applications accessing `$BOOT` should hence not assume that fancier file system features such as symlinks, hardlinks, access control or case sensitivity are supported.
For systems where the firmware is able to read file systems directly, `$BOOT` must be a file system readable by the firmware. For other systems, `$BOOT` must be a VFAT (16 or 32) file system. Applications accessing `$BOOT` should hence not assume that fancier file system features such as symlinks, hardlinks, access control or case sensitivity are supported.
