2 | efivarfs - a (U)EFI variable filesystem | ||
3 | |||
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. | ||
10 | |||
11 | Variables can be created, deleted and modified with the efivarfs | ||
12 | filesystem. | ||
