To remove any doubt we can launch the command into the chroot with

  echo " * Disabling startup of ssh-agent"
  chroot $INST_DIR sed -i [...]

However, I'd wait until bug #495795 [1] has been solved: if dropbear
would provide an scp client openssh-client won't be installed anymore,
which means that ssh-agent won't be present at all.

And then this would be a tip: if the user prefers openssh-client, he
should know how to disable ssh-agent ;-)

This problem is not related to openssh-client, but to dropbear instead.
However, which manual page have you read?  Both dropbear and dbclient
support remote command execution [2]:

=====

Again, I think we need test cases, since according to the dropbear
CHANGES [3], dbclient support zlib compression since version 0.47 (never
tested, I always use openssh-client).

Thx, bye,
Gismo / Luca
