Note that dropbear requires a per-device unique host key. The
|
|
|
|
|
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.
