Gateway old bug report to bugzilla:

... and /etc/init.d/rc.[1-6]d/ should be /etc/rc.[1-6].d
What more is there to
say?

Dan Quinland (FSSTND/FHS maintainer) told me the story on
how RH ended up using /etc/rc.d/ in the first place (by
misunderstanding the original FSSTND).

However, RH should be FHS compliant, and as much as the
change will be painful, everything has to be fixed to be in
/etc/{rc?.d,init.d}.

RH 6.0 could implement this and have a link from /etc/rc.d/
to /etc so that old contrib packages can keep working.
Before that, however, the upgrade should move all the
contrib files in /etc/rc.d/rc?.d in /etc/rc?.d

Not only will this make RH more compatible with other RPM
based distributions (including debian if you use alien), but
also other Unices like Solaris and Irix, and I'm sure many
others.

I know, it's a big and painful change, but I think it's
really worth it.
