Tags: ipv6
>From reading interfaces(5) for inet6/static, I had assumed that
specifying "privext 2" (or even 1) on a such an interface definition
would result in the behaviour of having both the statically-defined
address and the temporary/privacy ones.
However, the 'mngtmpaddr' flag is not set on the added address, which
means that the kernel will not manage (create/update/etc.) the
temporary addresses. Hence, the sysctl is then meaningless, as the
kernel has no "template" address from which to create one.
I've worked around my interface definition with a 'post-up ip a change
… mgntmpaddr', which seems to work and gives me the 2 addresses.
It might be that I misunderstand the inet6.defn file syntax however,
so if the error is on my part, let me know - I'll try to improve the
docs.
