Turris 1.x Btrfs kernel install can not find boot.scr

Package: turris1x-btrfs

root@turris:~# /usr/sbin/turris1x-btrfs-kernel-install
cmp: /boot/boot.scr: No such file or directory
cp: can't stat '/boot/boot.scr': No such file or directory

Caused by this !921 (merged)

Temporary workaround:

• remove this row deploy boot.scr from file: /usr/sbin/turris1x-btrfs-kernel-install

It's a thing, when boot.scr can not be found in folder /boot. See:

Package turris1x-support (5.4.203-1-f70e9c9745643e220f2338b431a1b5ff) is installed on root and has the following files:
/boot/turris1x.dtb
/boot/fdt
/boot.scr

Because of that a new kernel version is not installed.
