# I've added so many things like /etc/init.d/ to Slackware that CUPS
# is now installing init scripts to the Red Hat locations.  We'll move
# them to the usual locations:
#-- For ARMedslack these things don't get installed in the same locations
#

# Get rid of the SysV-style dir structure:
rm -rf $PKG/etc/rc.d
# And now put back the Slackware standard & install the rc script:
mkdir -vpm755 $PKG/etc/rc.d

# I'm not sure if overwriting this blindly could have ill effects,
# but it never hurts to play it safe.  According to the dbus-daemon
# manpage, only files ending in .conf will be used, so there won't
# be any unintended doubling up.

# However, this will get you the most useful SMB support for free.
