Markus, All,

On 2018-03-09 14:41 -0800, Markus Mayer spake thusly:
> Make the default PATH dropbear is using configurable.

We've discussed this with Thomas, and as Carlos noticed, we woudl need a
similar solution for openssh.

But pushing the thing even further, we think a generic solution is even
better:

  - in the "System configuration" sub-menu, add a new option that
    basically is "Default PATH" and defaults to /bin:/sbin:/usr/bin:/usr/sbin

  - use that to set PATH in /etc/profile (from the skeleton-init-common
    package)

  - use that for dropbear

  - use that for openssh

Care to have a look?

Regards,
Yann E. MORIN.
