Describe the bug

The efivarfs filesystem mounted at /sys/firmware/efi/efivars (which, if I understand correctly, shows EFI variables stored in NVRAM) is nearly full: df -h reports the filesystem is 148 kB in size, with 135 kB used and only 8.4 kB free.

If I run fwupdmgr get-updates, it attempts to install a "Secure Boot Signature Database Configuration Update", but this fails with the following error:

Update Error: Not enough efivarfs space, requested 16.4 kB and got 13.6 kB

Steps To Reproduce

Run df -h to check available free space in the efivarfs. I don't know how you'd reproduce this if the system doesn't already have this issue, but multiple people on the community forum are reporting the same issue:

• https://community.frame.work/t/efivars-full-on-framework-13-amd-7040-series/72997
• https://community.frame.work/t/cant-update-the-3rd-party-uefi-signature-database-due-to-lack-of-space-in-efivarfs/73432

Expected behavior

Presumably the efivarfs should either have more space or, if that's not possible, should manage the use of NVRAM in a way that avoids running out of space.

Operating System (please complete the following information):

• OS/Distribution: Fedora
• Version: 42
• Linux Kernel Version: 6.15.9-201.fc42.x86_64

Additional context

The largest entries in the efivarfs (according to ls -lS /sys/firmware/efi/efivars) are:

• dbx (20.7 kB)
• dbxDefault (17.8 kB)
• WIFI_MANAGER_IFR_NVDATA (4.7 kB)
• db (4.4 kB)
• dbDefault (4.4 kB)

All other entries are smaller than 3 kB each. There are 94 entries in total (most of them very small, under 100 bytes each), and adding up their sizes gives around 73 kB (notably much smaller than the 135 kB reported by df -h).
