[OpenWrt-Devel] [PATCH] dropbear: fix forever hanging startup when jffs2 fails to mount

[Bastian Bittorf]

if something goes wrong while mounting jffs2 (e.g. full flash
and the mount is readonly) the dropbear-init script will hang
forever (and so the startup-procedure) asking:

root at OpenWrt:~ /etc/init.d/dropbear boot
mv: overwrite '/etc/dropbear/dropbear_rsa_host_key'? <cursor blinking>

fix that by using 'mv -f' which omits the interactive question:

root at OpenWrt:~ mv -f /tmp/dropbear/dropbear_* /etc/dropbear/
mv: can't remove '/etc/dropbear/dropbear_rsa_host_key': Read-only file system

so the startup can continue.
