Package: initramfs-tools
Version: 0.131ubuntu8
Severity: normal
Tags: security

I have fully encrypted (UEFI, LUKS, BTRFS) system and in order to avoid typing 
password for the second time after GRUB2 added `keyscript` option to 
Keyscript file is only readable by root, however, resulting `initrd.img*` file 
is readable by anyone, which I think is a security issue.
I'd like to see `initrd.img*` files to also be readable by root user only.
