[SOLVED] How come I have efivarfs mounted as /sys/firmware/efi/vars in Slackware?
by hazel from LinuxQuestions.org on (#5QVCN)
While trying (and so far failing) to help a poster in the LFS forum, I was carrying out relevant searches on my own system and was surprised to find the UEFI variables mounted on /sys/firmware/efi/vars. There doesn't seem to be any reason for them to be there.
There is no entry for efivarfs in fstab; some distros have this but Slackware 14.2 does not. Systemd mounts this filesystem by default but of course that doesn't apply in Slackware. Kernel config shows the filesystem built as a module but it doesn't appear in lsmod. And I couldn't find an instruction to mount it in any of the startup scripts. So how did it get there?
