               where '-g' tells cvsup not to use a GUI, '-L 2' sets default output level to 2
            x for available cvs tags, look at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvs-tags.html
        o whats about daemon start-stop scripts (like at linux: /etc/init.d/) ?
+        x some daemons (only installed ports?) start-stop-scripts are placed at '/usr/local/etc/rc.d/'
+        o how at '/etc/rc.conf' toogled start-up scripts can be run manually(e.g. /etc/rc.firewall)?
        x configure and compile custom kernel:
          x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html
          x create custom kernel conf-file

            x  Use firewall_type = "OPEN" for default policy 'OPEN' (allow all)
+   - Linux & Wireless Lan:
+     x install modules:
+       x prims2 chipset based:
+         - if debian kernel-image is used
+            :#apt-get install linux-wlan-ng-modules-{your_arch}
+         - if not, cd to some temp dir and
+            :#apt-get source linux-wlan-ng   or wget sources manually if other dist is used
+            :#cd linux-wlan-ng-{version}
+            :#./Configure
+            :#make all install
+     x configure at debian:
+       x add SSID to dev at /etc/wlan/wlan.conf e.g.:
+          SSID_wlan0="WGATEWAY"
+          ENABLE_wlan0=y
+       x create and edit cutom config related to SSID
+         :#cp /etc/wlan/wlancfg-DEFAULT /etc/wlan/wlancfg-WGATEWAY
+         :#nano /etc/wlan/wlancfg-WGATEWAY
+     x notes!:
+        - prism2-based USB devices mostly needs hardware reset to get changes work!
+          this is caused of the firmware and could only be solved by a firmware-upgrade
+          of the vendor responsible for these devices.
+     o get WEP really work at heterogen enviroments(eg. between Win and Linux)
+     o WEP is unsecure! (see http://wepcrack.sourceforge.net/)
+       o use IPSEC
+       o or some other ideas?
+   - Linux & Bluetooth
+     With some tweaking bluetooth works as expected.
+     You will need the above mentioned patch patch-2.4.20-mh6 to have full functionality with 2.4.20. Then add
+       deb http://bluez.sourceforge.net/download/debian/woody/ ./
+       deb-src http://bluez.sourceforge.net/download/debian/woody/ ./
+     to your /etc/apt/sources.list for woody and install at least the packages "bluez-bluefw"
+     for loading the firmware into the usb bluetooth device. You will need "bluez-utils" for hci and rfcomm communications.
+     You need to add this line
+       bluefw 0x0003 0x044e 0x3001 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
+     to your /etc/hotplug/usb/bluefw.usermap to let the bluefw automatically load the appropriate firmware
+     into your dongle once it shows up.
+     I am using bluetooth with a Siemens S55, but e.g. Nokia 6310i goeas the same way.
+     For an initial pairing you will need a pin in /etc/bluetooth/pin which at least needs to have 5 digits which is documented near nowhere.
+     Once you do the pairing (Entered pin on the X requester popping up and on the cellphone) you can set your phone to not "Ask on connection".
+     Afterwards i put the rfcomm config into the /etc/bluetooth/rfcomm.conf
+     rfcomm0 {
+             device 00:02:EE:B8:50:C5;
+             channel 1;
+             comment "S55 Dialup connection";
+     }
+     rfcomm1 {
+             device 00:02:EE:B8:50:C5;
+             channel 9;
+             comment "S55 OBEX";
+     }
+     For dialing out via ppp you now can use /dev/rfcomm0 which should lead to your phone asking you to accept the connection.
+     For debugging you can use these commands:
+     :~$ sudo hcitool scan

+     - Hardware Notes:
+       x Broadcom 2033 chipset (tested with an ALLNET 7031 Class1 USB Adapter)
+         - Make sure you have bluefw and hotplug installed, then everything works fine right out of the box.
+          x on debian using default or for newer packages above sources:
+            :#apt-get install bluez-bluefw
+         - DO NOT enable the bluetooth.o module to avoid it being loaded by hotplug!!
+          x this can be done by adding  'bluetooth' to '/etc/hotplug/blacklist'
+            The Bluetooth device in this laptop is a USB Bluetooth device.
+            By default, Linux provides two different device drivers for USB Bluetooth devices: bluetooth.o and hci_usb.o.
+            The hci_usb.o is the correct driver for this device. Both drivers are loaded when the Bluetooth button is pushed
+            but unfortunately bluetooth.o obtains the device first, not allowing hci_usb.o to use the device.
+            In order for the Bluetooth device to be function, the bluetooth.o driver must not load.
+            One way to stop the bluetooth.o driver from loading is to remove the driver from the system. This is accomplished by doing:
+            :#rm /lib/modules/2.4.18-14/kernel/drivers/usb/bluetooth.o
+            :#depmod -a
+            Now, if inserting th usb device only the hci_usb.o should be loaded.
+   - ACPI
+     x get suspend work
+       - compile kernel with 'Software Suspend Support'
+       - some interesting post:

+       Last I checked, ACPI does suspend to memory or disk, using swsusp.  It's
+       even all integrated into the 2.5 kernels (though the CONFIG_SWSUSP option is
+       buried in the kernel hacking section rather than ACPI). If you don't want to
+       run an experimental kernel, then you can patch 2.4.x from the acpi.sf.net site.
