Sorry for my bad english, I am an Austrian,
i now that the pacman not provide the rc.d srcipts,
but i look at var/run/daemons and if the package is running then
i call /etc/rc.d/package stop but that is not the problem this is
working.

i have a own package and there a install script, which is calling
the /etc/rc.d/package stop if it is running and some colored messages,
the problem seems is about the tty:
pacman 2.7.9 says with the script;

/dev/vc/2

speed 38400 baud; line = 0;
-brkint ixoff -imaxbel
-iexten

pacman 2.8 says with the same:

not a tty

stty: standard input: Invalid argument

and this seems the problem, do you have any idea ?

here is my test install script:

post_install() {
tty
echo
stty
}

post_upgrade() {
post_install $2
}

pre_remove() {
/bin/true
}

post_remove() {
/bin/true
}

op=$1
shift

$op $*
