Furthermore, the kernel bug(s) referenced above seem to indicate that 'all' doesn't work quite right for things like use_tempaddr, and that the interface name must be used explicitly.

This may depend on the kernel & configuration [e.g. ipv6 as module]; setting "all" usually works, except in the IPV6_PRIVACY=yes case. When I remember correctly: You can set "all" and the setting will be visible in ethX/use_tempaddr, but is simply has no effect (no temp address gets assigned) until you set down & up the interface, because the autoconfig already happened [or it is already running using the old setting].

Am I wrong to conclude that

a) the init script in openSUSE 11.4 /as of this writing/ is not working properly (it is clearly writing to 'default' which only works for interfaces brought up after)

No, this is not a wrong conclusion. Currently the best way is to set it in /etc/sysconfig/network/ifsysctl; when needed, also per interface. See "man 5 ifsysctl". It is applied twice: via udev as soon as an interface appears and then also before ifup calls "ip link set up", ...

b) it should write to *both* default *and* all *and* all interfaces[1], since 'all' does NOT appear to work?

Well.. to catch all interfaces "all" *would* be correct -- when it would have an effect. In the hope, that the setting gets applied early enough, we set "default" as it works for new interfaces. Maybe it would be a not so bad idea to set both to increase the hope :-)

[1] -- how hard to fix the kernel vs. the init script such that writing to 'all' really changes 'all' ?

This seems to be same with writting E-Mails to /dev/null. Note, that the referenced kernel.org reports about are from 2007 & 2008 and still "NEW". We are adding & fixing strange workarounds because of this since years... As Jiri already wrote in comment referenced above "The change may never get there [upstream], people have different ideas about how this should work :(".
