IIRC, /boot/efi/* is created by the initial anaconda install sequence

it's only about 15MB in size, it's pretty innocuous and I wouldn't
worry about it. Ubuntu's install mechanism isn't the same and it
probably doesn't create that directory unless it notices you are in UEFI
boot mode at the time of install.

What's in yours?  Are any of the files owned?  Mine is just an empty directory tree to /boot/efi/EFI/fedora/.  I just checked further and that directory is owned by grub-common, but not the parent directories.

I've just checked my efi directory, and /boot/efi is owned by 'root', as are directories /boot/efi/EFI and /boot/efi/System and file /boot/efi/mach_kernel. Drilling a little bit further directories /boot/efi/EFI/BOOT and /boot/efi/EFI/fedora are also owned by root, as is directory /boot/efi/System/Library, so I'm assuming everything is.

Sorry for not being more clear.  I mean owned in the rpm way.  If you do "rpm -qf /path/to/file" it will tell you which package put the file (or directory) there.

I'm not concerned so much by the space that structure is using, but more just querying why it is there, and, if I happen to delete that structure will that cause any problems, or, if I do delete it is something going to put it back?

If you don't have an EFI system, then deleting those files shouldn't make any difference.  But I'm curious, since you actually have files in there, can you check what package owns them as described above?

I've issued the command rpm -qf /boot/efi and it tells me it was owned by fwupdate-efi-10-1.fc27.x86_64.

I've also issue the command rpm -qf /boot/efi/EFI/fedora/grubenv and that is owned by grub2-efi-x64-2.02-19.fc27.x86_64.

The command rpm -qf /boot/efi/mach_kernel tells me it is owned by mactel-boot-0.9-16.fc27.x86_64.

rpm -qf /boot/efi/EFI/fedora/grubx64.efi says it is owned by grub2-efi-x64-2.02-19.fc27.x86_64.

rpm -qf /boot/efi/EFI/fedora/shim.efi says it is owned by shim-x64-13-0.7.x86_64.

I haven't issued the command against the other .efi files in the fedora sudirectory, but from their names I would assume they are owned by multiple different packages. The thing that sticks out with these .efi files in the fedora directory is that fwupia32.efi and fwupx64.efi are executable by owner which is root, but grubx64.efi is world executable, and, those 3 files are the only ones of the 8 .efi files present that are executable.

Steve
