説明文
BR2_PACKAGE_DROPBEAR:

Note that dropbear requires a per-device unique host key...
key will be generated when dropbear starts, but it is not
persistent over reboot (if you have a read-only rootfs) or
upgrade (if you have a read-write rootfs). To make the key
persistent, replace /etc/dropbear with a symlink to a
directory on a persistent, writeable filesystem.
Alternatively, mount a persistent unionfs over your root
filesystem.

Note that dropbear requires a per-device unique host key...
key will be generated when dropbear starts, but it is not
persistent over reboot (if you have a read-only rootfs) or
upgrade (if you have a read-write rootfs). To make the key
persistent, replace /etc/dropbear with a symlink to a
directory on a persistent, writeable filesystem.
Alternatively, mount a persistent unionfs over your root
filesystem.
