• An edit of the existing instructions.

Description ∞

Booting straight into Debian with the Sharp Zaurus SL-series.

The developer is using a stock Sharp ROM.

TODO – Test it with Cacko.

Issues ∞

• Building the keymap to SL-C3100 under the Debian environment.

  • This means that it doesn’t have the keymap which has the mapping of the ‘/’ command.

Screenshots ∞

Like this, but with CPU Utilization only 20-30%, with a dark-green background, and some small battery signals/keyboard signs in the right-top corner.

Very similar to Meanie’s capture screen in X/Qt but with CPU Utilization only 20-30%, with a dark-green background, and some small battery signals/keyboard signs in the right-top corner on the following screen …

The actual screen’s battery meter & keyboard icons are not present in this screen. The real CPU utilization (bottom-right) would be less, but this was captured with UltraVNC.

Using UltraVNC as the capturing tool, i just managed to capture the VNC screen… but the actual screen’s battery meter & keyboard icons are not present in this screen…

plz also note that the CPU utilization is greatly reduced in the right bottom corner…

Debian/PocketWorkstation dual-booting with Qt ∞

How to dual-boot Debian / PocketWorkstation with Qtopia in the Sharp Zaurus SL-series.

Optional ∞

Telnet is optional.

Optional equipment:

• A CompactFlash (CF) LAN / WiFi card, to Telnet into the Zaurus inside if issues occur

• A large-capacity SecureDigital (SD) card, if your Zaurus does not have a large internal storage capacity.

  • The Zaurus SL-C3000 and higher have a local MicroDrive which is large enough.

Preparation ∞

1. Download zaurus-debian-big-v0.18.tgz

2. If your Zaurus has no tcpip configured, enable it with the Qtopia Network GUI / applet.

   • Install the sudo ipk if it is absent. (It comes with Cacko.)
3. enable telnetd inside your Zaurus

4. For the fastest performance, you can directly format your SD card into ext2 format; but for MD-equipped Zauri, a loop device is also a good choice for loop filesystem mounting

   • My mount-point choice is /hdd3/debroot with a loop device called /hdd3/debian.fs

Build debian.fs ∞

su
cd /hdd3
mkdir debroot
dd if=/dev/zero of=/hdd3/debian.fs bs=1M count=768 (i create a 768M loop device)
echo y | /sbin/mke2fs debian.fs
mount -o loop -t ext2 /hdd3/debian.fs /hdd3/debroot

Build swap file ∞

Please also note that a swapfile needs to be built (around 256M is suggested). (Background details)

su
dd if=/dev/zero of=/hdd3/swapfile bs=1M count=256
mkswap /hdd3/swapfile

• Cacko 1.23 has a swapfile tool built in.

  • Click the cpu monitor next to the clock. Then pick the “swapfile” tab.
  • (date not recorded) — I tried this and it hung.

Modify fstab ∞

fstab: /etc/fstab

/hdd3/swapfile                                   swap    defaults           0  0
/hdd3/debian.fs                 /hdd3/debroot    ext2    loop               0  0

Prepare debroot ∞

Extract the tar.gz:

zcat zaurus-debian-big-v0.18.tgz | tar xvf - -C /hdd3/debroot

postinst.sh ∞

In the /hdd3 directory, run ./debroot/INSTALL.d/postinst.sh

• All questions should be answered y / yes

  • except the last question: Run ‘Fbvnc’ now? (answer no)

edit Fbvnc ∞

vi /usr/local/bin/Fbvnc

NOTE: Many model numbers have been tried, and -hw c700 seems to be the best.

You are welcome to try other hardware model numbers and tell Dinorex if you find a better one.

if [ -z "$1" ]; then
       fbvnc -hw c700 127.0.0.1:1
else
       fbvnc -hw c700 "$@"
fi

edit debroot.conf ∞

vi /etc/debroot.conf

DEBROOT=/usr/mnt.rom/card

DEB_PATH=$HOME/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/games

#DEB_QPE_WARNING=1

DEB_DO_MOUNTS=1

DEB_COPY_INTO_CHROOT="etc/resolv.conf"

DEB_COPY_INTO_NATIVE="etc/hosts"

#DEB_RUN_SERVICES=""
#DEB_RUN_SERVICES="inetd ssh lpd"
#DEB_RUN_SERVICES="ssh"

DEB_RUN_VNCSERVER=1

DEB_RUN_FBVNC=1

DEB_ZAPM_PROXY=1

DEB_RUN_ZAPMD=1

DEB_ROOTCMD=1

Delete the zdebian symbolic link ∞

In the /etc/rc.d/ directory tree, find the symbolic link to zdebian and delete it.

In my case it was:

rm /etc/rc.d/rc5.d/S99zdebian

edit zdebian ∞

vi /etc/rc.d/init.d/zdebian

Change the first line to #!/bin/bash

TODO – make a little script to prepend that.

create sw-deb.sh and sw-qt.sh ∞

In /usr/local/bin/, create these two files:

sw-deb.sh ∞

vi /usr/local/bin/sw-deb.sh

#!/bin/sh
clear
echo "zdebian stop.."
/etc/rc.d/init.d/zdebian stop
echo "kill Xvnc.."
echo "change launch.default to 'q'"
echo q > /home/zaurus/launch.default
echo "DONE."
exit 0

chmod 755 /usr/local/bin/sw-deb.sh

sw-qt.sh ∞

vi /usr/local/bin/sw-qt.sh

#!/bin/sh
echo a > /home/zaurus/launch.default
sudo /sbin/reboot
killall qpe
killall qpeserver
killall qtsamba
clear
/home/root/usr/bin/chvt 2
/home/root/usr/bin/chvt 1
exit 0

chmod 755 /usr/local/bin/sw-qt.sh

create launch.default ∞

echo "echo a > launch.default" > /home/zaurus/launch.default

create startd ∞

vi /usr/local/bin/startd

#!/bin/sh
clear
sudo /bin/mount -o bind /mnt/card /hdd3/debroot/mnt/card
sudo /sbin/swapon /hdd3/swapfile
sudo ./zdebian start

chmod 755 /usr/local/bin/startd

edit rc.rofilesys ∞

Mount the filesystem as read/write. See Remounting Filesystem as Read/Write or Read Only.

Add the zdebian ‘dual-boot’ flag:

vi /root/etc/rc.d/rc.rofilesys

FIXME — This isn’t very well-described. Where should this text go, at the bottom?

Mount the filesystem as read only. See Remounting Filesystem as Read/Write or Read Only.

Usage / Notes ∞

Remounting Filesystem as Read/Write or Read Only ∞

http://www.users.on.net/~hluc/myZaurus/custom.html

Some partitions/file systems such as / cannot be unmounted. Some are also mounted as read-only. In order to modify the files on those file systems, you need to remount them as read/write and then remount them back to read-only after you have done what you wanted.

To remount as read/write:

mount -o rw,remount /

To remount as read only:

mount -o ro,remount /
