2 efivarfs - a (U)EFI variable filesystem
4 The efivarfs filesystem was created to address the shortcomings of
5 using entries in sysfs to maintain EFI variables. The old sysfs EFI
6 variables code only supported variables of up to 1024 bytes. This
7 limitation existed in version 0.99 of the EFI specification, but was
8 removed before any full releases. Since variables can now be larger
9 than a single page, sysfs isn't the best interface for this.
11 Variables can be created, deleted and modified with the efivarfs
14 efivarfs is typically mounted like this,
16 mount -t efivarfs none /sys/firmware/efi/efivars
