Is it possible to see output on stdout and stderr of the script without the user confirmation via feddback tag?

no, it's not possible but maybe not a bad idea to implement it for the future. I put it on my TODO (or at least on my TOLOOKAT) list. ;)

The way I handle it is to make my scripts chvt to an unused console and then explicitly redirect the output to that console. At the end of the script, it switches back to the original console.

For example (from a chroot-script):

CURVT=`chroot /mnt /bin/fgconsole` [ -z "$CURVT" ] && CURVT=1 NEWVT=16; DEVVT=/dev/tty$NEWVT chroot /mnt /bin/chvt $NEWVT # If this is a serial console, we should write there instead cons=`sed 's/.*console=([^ ,]*).*/\1/' /proc/cmdline` case "$cons" in ttyS*) DEVVT=/dev/$cons ;; *) DEVVT=/dev/tty$NEWVT ;; esac

echo "Starting script (`date`):" > $DEVVT

if grep -q '<debug>' /proc/cmdline; then echo "debug: spawning shell" > $DEVVT setctsid $DEVVT /bin/sh fi

[...]

Something similar (without the chroots) should work for postinstall scripts.
