I needed to recreate my systemd-boot’s EFI boot entry in an oldish system converted from Grub. I did a `sudo bootctl install` and I got the output here below: ```auto Copied "/usr/lib/systemd/boot/efi/systemd-bootx64.efi" to "/efi/EFI/systemd/systemd-bootx64.efi". Copied "/usr/lib/systemd/boot/efi/systemd-bootx64.efi" to "/efi/EFI/BOOT/BOOTX64.EFI". ⚠️ Mount point '/efi' which backs the random seed file is world accessible, which is a security hole! ⚠️ ⚠️ Random seed file '/efi/loader/random-seed' is world accessible, which is a security hole! ⚠️ Random seed file /efi/loader/random-seed successfully refreshed (32 bytes). Created EFI boot entry "Linux Boot Manager". ``` I have done a quick search in www but I haven’t found anything related to these warnings. Does anyone know what these are about and how I could fix it? `drwxr-xr-x 8 root root 4096 Jan 1 1970 efi` ```auto ls -al /efi/loader/ total 24 drwxr-xr-x 3 root root 4096 Aug 1 22:27 . drwxr-xr-x 8 root root 4096 Jan 1 1970 .. drwxr-xr-x 2 root root 4096 Jun 16 19:22 entries -rwxr-xr-x 1 root root 6 Sep 15 2022 entries.srel -rwxr-xr-x 1 root root 71 Apr 26 20:47 loader.conf -rwxr-xr-x 1 root root 32 Aug 1 22:27 random-seed ``` ---

Thank you so much @dalto for the swift reply! I executed the two chmod commands. I ran the` bootctl install` once again to test. I’m still getting: ```auto ⚠️ Mount point '/efi' which backs the random seed file is world accessible, which is a security hole! ⚠️ ⚠️ Random seed file '/efi/loader/random-seed' is world accessible, which is a security hole! ⚠️ ``` What am I missing? ---

```auto $ ls -ld /efi drwxr-xr-x 8 root root 4096 Jan 1 1970 /efi ``` It seems that the chmod command didn’t change any permissions? ---

> [@pebcak](#): > > It seems that the chmod command didn’t change any permissions? Hahaha…it is because it is fat32. You need to change the permissions in `/etc/fstab` and remount it. Maybe add `fmask=0137,dmask=0027` to options. ---
