After having observed some bizare error output during shutdown I opted for the following rc.shutdown script in slitaz-boot-scripts package
----------------------

#!/bin/sh
#
# /etc/init.d/rc.shutdown : Executed on system shutdown or reboot
#
. /etc/init.d/rc.functions
. /etc/rcS.conf

log=/var/log/shutdown.log

# Clear and quiet shutdown
clear && echo "System is going down for reboot or halt."
uptime

# Store last alsa settings.
echo "Store last alsa settings..."
if [ -x /usr/sbin/alsactl ]; then
alsactl store
fi

# Stop all daemons started at boot time.
echo "Stop all daemons started at boot time..."
for daemon in $RUN_DAEMONS
do
if [ -x /etc/init.d/$daemon ]; then
/etc/init.d/$daemon stop
fi
done
if [ "$SCREEN" != "text" ] && [ "$LOGIN_MANAGER" ]; then
echo -n "Stopping dbus daemon..."
/etc/init.d/dbus stop
echo -n "Stopping login manager daemon..."
/etc/init.d/$LOGIN_MANAGER stop
fi

if [ "$UDEV" == "yes" ]; then
echo "Stopping udev daemon..."
udevadm control --exit
echo "Udevadm waiting for the event queue to finish..."
udevadm settle --timeout=120
fi

# Stop networking
echo -n "Stopping the network interfaces..."
/etc/init.d/network.sh stop

# Sync all filesystems.
echo "Sync all filesystems..."
sync

# Swap off.
echo "Swap off..."
/sbin/swapoff -a

# Kill all processes.
echo "Kill all processes..."
killall5

# Umount filesystems.
echo "Unmount filesystems..."
/bin/umount -a -r

Thanks for trying, unclean shutdown on cooking persists.
On reboot:
Checking filesystem: /dev/sda1
/dev/sda1 was not cleanly unmounted, check forced.
/dev/sda1: 11308/68256 files (5.2% non-contiguous), 97173/272640 blocks

also to avoid hanging at shutdown due to network mounts unmounted after stopping the network
the following needs to be added before network.sh stop

# Unmount network filesystems before stopping the network
echo "Unmounting network filesystems CIFS/NFS etc..."
umount -t cifs,nfs,nfs4,smbfs,ncp,ncpfs,coda,ocfs2,gfs -a -f -l

@mojo
hmm... does moving the sync just before the final umount (thus after the killall) fixes your issue?

Unclean shutdown persists.

@mojo
it can be tricky to debug the shutdown sequence.

have you tried to shutdown from a tty console to see if you get the same ?
I'd first disable the graphic login in rcS.conf and then reboot to get to the tty console prompt and login. then sync and poweroff and see if the problem with sda1 is still there.

if you still get "/dev/sda1 was not cleanly unmounted, check forced." you should also check the options used by umount; if there is the -f option and sda1 is kept busy by some process then this may cause sda1 to be "not cleanly unmounted"; you should try to find this process... is it some daemon which is not stopped ?
first I'd remove the -f and look for some error message from the umount command
I'd then put
ps aux > /root/shutdbg-ps.log
lsof > /root/shutdbg-lsof.log
just before the umount command in rc.shutdown and I'd inspect the logs to find some clue of a process keeping sda1 busy.

Hi, after some attempts i think to have found a possible solution at the problems in rc.shutdown
script; at the end, before umount all file system:

# Umount filesystems.
/bin/umount -a -r 2>/dev/null

insert these lines:

while [ -e /run/udev ]; do
        rm -r /run/udev
done

so:

#!/bin/sh
# /etc/init.d/rc.shutdown - This script is used by /etc/inittab to stop
# all daemons and shutdown the system.
#
. /etc/init.d/rc.functions
. /etc/rcS.conf

log=/var/log/shutdown.log

# Bold info message with uptime
clear && echo "System is going down for reboot or halt." > $log
uptime >> $log

# Store last alsa settings.
if [ -x /usr/sbin/alsactl ]; then
        alsactl store
fi

# Stop all daemons started at boot time.
for daemon in $RUN_DAEMONS
do
        if [ -x /etc/init.d/$daemon ]; then
                /etc/init.d/$daemon stop >> $log
        fi
done

# Sync all filesystems.
sync

# Swap off.
/sbin/swapoff -a

# Kill all processes.
killall5

while [ -e /run/udev ]; do
        rm -r /run/udev
done

# Umount filesystems.
/bin/umount -a -r 2>/dev/null
