Somehow sysv init never ran into this issue. Maybe it's okay to let the kernel seed its entropy pool before initializing your hash table.

I don't think sysvinit made use of hashtables, and if they did they would probably hit the same snag.

sysvinit (or rather RC systems often built on top of it) tended to use trees (most often the filesystem). Unlike hash-tables, trees don't need randomness to guarantee asymptotic behavior.
