I realise it's 3 days before release weekend, this upload fixes a problem
that we can't really fix in a security update. Yesterday a user discovered
that their encryption key for their hard disk in a full-disk-encryption
setup is world-readable on debian-based systems using initramfs-tools.

This affects Calamares users who can now install Debian on in an easy to
use full-disk encryption setup. Upstream bug:
https://github.com/calamares/calamares/issues/1191

CVE:
https://nvd.nist.gov/vuln/detail/CVE-2019-13179

This upload updates the bootloader-config script with this additional snippet:
"""
# Set secure permissions for the initramfs,
# the initramfs is re-generated later in the installation process
# so we only set the permissions without regenerating the initramfs now:
echo "UMASK=0077" > $CHROOT/etc/initramfs-tools/conf.d/initramfs-permissions
"""

Which will cause "update-initramfs -u" that runs later in the script to write
the initramfs with safe permissions.

Without this upload, users will have to write that file theirselves in order
to have a setup safe from local users (or users on the system with filesystem
access). In such a case we'll note it in the release notes, but I would urge
the release team to consider it if there is still any possibility.
