With the recent addition of halevt in Gentoo’s portage<\/a> it is now relatively easy to automatically mount media like USB sticks and CD\/DVD discs on \/media. <\/p>\n

What I wanted to do was to emulate my previous set of configs<\/a> and scripts<\/a> that ivman used to create icons of automatically mounted media on ROX desktop (called pinboard)<\/a>. I am using ROX pinboard on top of my favorite window manager, fluxbox<\/a>.<\/p>\n

The idea is that halevt<\/a> is started by the fluxbox startup config file and when a new device is attached to the computer, halevt config calls a script that creates an icon on the ROX pinboard using ROX rpc. When a device needs to be removed ROX pinboard is configured to call a special eject command that checks for a couple of things before unmounting the device and calling the script to remove the icon from ROX pinboard.
\nApart from automatically mounting\/unmounting of devices I have also added a nice option in the halevt config to unmount and eject the CD\/DVD drive when the eject button on the device is used and of course when the CD\/DVD is not in use. That emulates a bit the windows behavior that so many users have gotten used to.<\/p>\n

Since the script used by halevt involves a lot of file reading\/writing and parsing I thought it would be wise to convert my old rox.panelput bash script<\/a> to perl. And I was correct, the speed difference, even for such simple tasks is more than noticeable.<\/p>\n

The installation process<\/strong>. Please take notice of the user executing the commands, $ is for normal user, # is for root:
\n0) create \/usr\/local\/bin\/ path and put it in your shell’s PATH<\/strong>
\n# mkdir \/usr\/local\/bin
\n$ echo \"export PATH=$PATH:\/usr\/local\/bin\/\" >> ~\/.bashrc<\/code><\/p>\n

1) install halevt<\/strong>
\n# echo \"sys-apps\/halevt ~x86\" >> \/etc\/portage\/package.keywords
\n# emerge halevt
\n<\/code>
\n
\n2) create ~\/.halevt\/HalevtConfigActions.xml<\/strong> in your home directory:
\nFile: HalevtConfigActions.xml<\/a> (right click->Save-as)<\/p>\n

3) Create \/usr\/bin\/eject.hal<\/strong>. Take notice that the script uses bash and not dash!
\n

#!\/bin\/bash\nif [ -z $1 ]; then\n    echo "Usage: eject.hal <device>"\n    exit\nelse\n  echo "$1" | egrep "^\/dev"\n  if [ "$?" == "0" ]; then\n    #echo "Device First, find mount point"\n    TOSCAN=`echo "$1" | sed -e 's\/ \/\\\\\\\\\\\\\\\\040\/g'`\n    TOUMOUNT=`grep "$TOSCAN" \/proc\/mounts | cut -d" " -f2`\n    UDI=`hal-find-by-property --key volume.mount_point --string "$TOUMOUNT"`\n    DISC=`hal-get-property --udi "$UDI" --key volume.is_disc`\n    \/usr\/local\/bin\/rox.panelput.pl Remove "$TOUMOUNT"\n    halevt-umount "$1"\n    halevt-umount -s\n    if [ "$DISC" == "true" ]; then\n        \/usr\/bin\/eject -p "$1" &>\/dev\/null\n    fi\n  else\n    #echo "Mount Point First, find device"\n    UDI=`hal-find-by-property --key volume.mount_point --string "$1"`\n    DISC=`hal-get-property --udi "$UDI" --key volume.is_disc`\n    TOSCAN=`echo "$1" | sed -e 's\/ \/\\\\\\\\\\\\\\\\040\/g'`\n    TOUMOUNT=`grep "$TOSCAN" \/proc\/mounts | cut -d" " -f1`\n    \/usr\/local\/bin\/rox.panelput.pl Remove "$1" nowait\n    halevt-umount "$1"\n    halevt-umount -s\n    if [ "$DISC" == "true" ]; then\n        \/usr\/bin\/eject -p "$TOUMOUNT" &>\/dev\/null\n    fi\n  fi\nfi\n<\/device><\/code2><\/pre>
\nFile: eject.hal<\/a><\/p>\n
4) Create \/usr\/bin\/rox.panelput.pl<\/strong> perl script. The script is written very simplistically to be easily understandable and changable.
\nFile: rox.panelput.pl<\/a><\/p>\n
5) Start halevt from fluxbox startup<\/strong>..make sure ~\/.fluxbox\/startup<\/strong> file contains at least the following, changing YOURUSERNAME to the one appropriate:
\n\/usr\/local\/bin\/rox.panelput.pl Restore
\nkillall -9 halevt; halevt -f -u YOURUSERNAME -g plugdev &
\n\/usr\/bin\/rox -p pinboard<\/code><\/p>\n
6) go to ROX options and change ‘eject command’ to use eject.hal<\/strong>
\n\"rox-using-eject-hal-screenshot\"<\/a><\/p>\n
That should be all. Upon fluxbox restart halevt should start and when you plug in your usb the set of scripts will create an icons on ROX pinboard for you.<\/p>\n
Example:
\n\"usb-mounted-by-halevt-and-rox.panelput.pl\"<\/a><\/p>\n
