Sure, some words are out of order, but it makes sense to me.
What about this :
"Can I somehow, through local configuration or configuration of
radvd on the router, ensure that the SLAAC address
is taught as "deprecated", making the statically configured address
suitable for outgoing connections ? Unfortunately, nagios check_ssh
plugin cannot set the source address."

Maybe there is a misunderstanding in the meaning of "preferred". I did
not mean it as "recommended practice". I just mean that in my
experience, when a Linux host has both statically assigned and
autoconfigured IPv6 addresses in the same prefix, the IPv6 stack always
select the statically assigned address by default. This makes sense to
me, because through static assignment the administrator wants the host
to use that specific address.
