dropbear generates its keys at the first connection, and wants to save
them in /etc/dropbear (not configurable).
Currently, our /etc/dropbear is a directory.
When the filesystem is read-only, dropbear can't save its keys, so
refuses all connections.
Fix that with:
- at build time, create /etc/dropbear as a symlink to
/var/run/dropbear
- at runtime, if the filesystem is RW (we can rm /etc/dropbear),
we replace the symlink with an actual directory; otherwise,
when the filesystem is RO (we can't rm /etc/dropbear), we create
/var/run/dropbear so the symlink points to an existing directory

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
