All sysconf values behave like that :)

This is probably because lvs is a module and thus that directory isn't
available until the module is inserted. And presumably the call to
sysctl -p during the init process is occuring after that.

A fine hack indeed. Onother work around might be to add ip_vs to
/etc/modules. I'm not sure if that gets processed early enough to help
your problem, but it would be worth checking.
