Hello all, I've recently been trying to compile s6 and family on OpenBSD and I indirectly came across a bug (if that's the correct term here) in skalibs. skalibs compiles and installs without issue. However, when I compile s6, one of the programs fails to link (I didn't pay attention to which one), with the linker complaining about an undefined reference to arc4random_addrandom().
Long story short, after searching through the skalibs source, OpenBSD's manpages and OpenBSD's CVS, I found that OpenBSD removed the arc4random_addrandom() and arc4random_stir() functions in 2013. I tried commenting out the body of random_init() in librandom (where the offending invocation of arc4random_addrandom() occurs) and recompiling skalibs, after which s6 would link correctly. s6 appears to be working properly with this change to skalibs, but I don't know how it could be impacting the internals of s6 and friends. Regards.
