-# This class installs additional files found on the build host
-# directly into the rootfs.
-#
-# One use case is to install a constant ssh host key in
-# an image that gets created for just one machine. This
-# solves two issues:
-# - host key generation on the device can stall when the
-# kernel has not gathered enough entropy yet (seen in practice
-# under qemu)
-# - ssh complains by default when the host key changes
-#
-# For dropbear, with the ssh host key store along side the local.conf:
-# 1. Extend local.conf:
-# INHERIT += "rootfsdebugfiles"
-# ROOTFS_DEBUG_FILES += "${TOPDIR}/conf/dropbear_rsa_host_key ${IMAGE_ROOTFS}/etc/dropbear/dropbear_rsa_host_key ;"
-# 2. Boot the image once, copy the dropbear_rsa_host_key from
-# the device into your build conf directory.
-# 3. A optional parameter can be used to set file mode
-# of the copied target, for instance:
-# ROOTFS_DEBUG_FILES += "${TOPDIR}/conf/dropbear_rsa_host_key ${IMAGE_ROOTFS}/etc/dropbear/dropbear_rsa_host_key 0600;"
-# in case they might be required to have a specific mode. (Shoundn't be too open, for example)
-#
-# Do not use for production images! It bypasses several
-# core build mechanisms (updating the image when one
-# of the files changes, license tracking in the image
-# manifest, ...).
