Some things put stuff in Slackware's /etc/init.d, but this is unusual.
❰jayjwa❙/etc❱✔≻ ls init.d/
functions*  README.functions  xrdp*

I don't actually use that script anyway.

In Solaris 9, /etc/rc.d is obsolete, according to /etc/init.d/README:

NOTE:

/sbin/rc2 has references to the obsolescent 'rc.d' directory.  These
references are for compatibility with old INSTALL scripts. New INSTALL
scripts should use the init.d directory for related executables.  The
same is true for the shutdown.d directory.

This is what SysVinit looks like on Solaris 9:

There's no /etc/rc.d.

Looks like Slackware's is patterned off of BSD but with some
modifications. There's a rc.sysvinit but I've never seen it used in all
my years of Slackware.
