dropbear: drop run time detection of read-only rootfs
Previously, when dropbear was started via its init script, relocation of DROPBEAR_RSAKEY_DIR to support read-only rootfs was handled at run time from within the init script. Update the init script to take advantage of the read-only rootfs config setup by read_only_rootfs_hook() and therefore be consistent with startup under systemd (where relocation of DROPBEAR_RSAKEY_DIR is handled by the read_only_rootfs_hook() at build time). (From OE-Core rev: 4990f87b2f6a8b30c8d1c767636e7f5527f595ba) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
