Hi,

I'm running into an issue on RedHat: rc.subr has _RCCMD_su="/usr/bin/su"
but su on Linux is in /bin/su. Same issue appears to be there on
Debian/Ubuntu, but I don't have a Slackware machine or other Linuxes to
look at.

I looked for any other issues with rc.subr in general and found none.
Here's a patch...
