/etc/grub2.cfg Flagged a Potenially missing

[Stephen Morris]

Hi,
     /etc/extlinux.conf is flagged as missing, the file is displayed in 
red and the link is shown in white text on a red background. As 
mentioned in another thread on this list that file actually is missing.
     /etc/grub2.cfg and /etc/grub2-efi.cfg both of which point to the 
same file also display the same way as /etc/extlinux.conf, but in this 
case the file pointed to actually does exist, and is linking to 
/boot/grub2/grub.cfg, which I regularly write to with sudo and 
grub2-mkconfig, but I have also found that I need to use sudo to browse 
/boot/grub2. Is it normal for links to be flagged as missing when sudo 
is required to list the contents of the directory and why is sudo 
required to list the contents of /boot/grub2 when I don't need sudo to 
list the contents of /boot? /boot/efi seems to be in the same situation.

regards,
Steve

flagged as missing by what? This file is normally not created on any Fedora variant
I'm aware of. It could be a legacy file.

There is no reason to regularly replace grub.cfg, it's a static file these days. The
files that change are drop-in files found in /boot/loader/entries and can be modified with
grubby per examples at:

I don't use grubby I use grub2-mkconfig because I don't like the grub 
boot menu that grubby produces, and I use grub2-mkconfig to build the 
grub menu for tri-booting between Windows 11, Fedora 36 and Ubuntu.

sudo/root is required to access the grub subdirectory because the
permissions are locked down.

I would guess since there can be encrypted grub passwords (and
possibly other similar stuff) in there that is why it is locked down.

I did check
the acl on the folder and noticed it was locked down to 
root. I could put an acl on the folder to make the folder readable by me 
without enabling reading of the contents of the files in that folder, 
but is that the only way to stop ls from flagging a file as deleted when 
the parent folder is locked down?

Steve

Pretty much.

From the command run as a real user the file does not exist because of
permissions, but the command has no way to know that so it is simply
missing.

Thanks Roger, I thought that might be the situation.
