User-interactivity in %pre

[Daniel Segall]

Speaking of which....

Has anyone experienced any problems with this on FC3? For some reason, my
dialog boxes aren't showing up properly since I started testing FC3 a
while back. I have to (blindly) hit enter on my first prompt, then the
next one (which requires input) will show up, then the next yes/no box
doesn't show up either.

I know that's probably not the best explaination, but It's hard to
describe. Any ideas? Here's the chunk of my %post:


%post --interpreter /bin/sh
exec < /dev/tty3 > /dev/tty3
chvt 3

---snip---
Some random package stuff here
---snip---

# Execute our post install
echo "  "                                       >>/root/ks.log
if [ -f /root/linux-postinstall.sh ]; then
        echo " * Executing Post-Install..."     >>/root/ks.log
        echo " * Executing Post-Install..."
        chmod +x /root/linux-postinstall.sh
        exec /root/linux-postinstall.sh         >>/root/ks.log
else
        echo "Can't find linux-postinstall.sh." >>/root/ks.log
        echo "Can't find linux-postinstall.sh."
fi

# We done.
echo " * Post-Install complete. System rebooting." >>/root/ks.log
echo " * Post-Install complete. System rebooting."
chvt 1
