udev and autofs mount of usbdisks

[brandtdaniels]

Create script to auto mount any inserted USB storage and search for any ".nes" files on that storage. Use the list of files found to generate a basic text menu that can be navigated using a nes controller. have the selected rom start up in the emulator.

I should have just put this in here instead of in an email:

I'd like to get a release out this week. Can we do the following with the auto-mount script?

• User inserts USB stick, which is auto mounted
• All .nes files are copied to /root/roms
• Launch executable /root/glint-es/glint-es &> /root/gn.log (this log file helps me troubleshoot problems with EmulationStation)

[brandtdaniels]

Couple of things:

Copying files takes some time. Can we have ES first look in /root/roms then look in /mnt/usbdisk? I would rather have it just read my roms off the stick. This will avoid duplication or whatever other mess it could cause.

Second, logs should go in /var/log(s)/glint/gn.log

Yeah, I think that should be doable. Will the mount point always be called usbdisk or can it sometimes have a number after it or something else that prevents the name from being the same 100% of the time?

You have a good point about duplicatation, didn't think of that.

I'll start putting the log in the /var/log folder.

It might need testing but I've set it up so udev changes sd?[1-9] to usbdisk%n and autofs mounts anyone of those to /mnt/usbdisk

Sounds pretty good. Can you commit it to a topic branch on the repo or send it to me?

Unless you're still tweaking it, that is.

[brandtdaniels]

the only thing that needs to be fleshed out more is the autofs file auto.ext-usb:

usbdisk -fstype=auto :/dev/usbdisk1

need to see if the 1 can be a matching statement such as [1-9]

[brandtdaniels]

Created a script for this if you want to integrate:

#!/usr/bin/env bash
#install autofs and udev
sudo apt-get -y install autofs udev
#create the mount point
sudo mkdir -p /mnt/usbdisk
#create a new udev rules file and add line
sudo echo -n 'ACTION=="add", SUBSYSTEM=="block", KERNEL=="sd?[1-9]", SYMLINK+="usbdisk%n", RUN+="/usr/local/bin/copyroms.sh"' > /etc/udev/rules.d/80-usbdisk.rules
#restart udev
sudo /etc/init.d/udev restart
#add line to autofs file auto.master
sudo echo "/mnt /etc/auto.ext-usb --timeout=10,defaults,user,exec,uid=1000" >> /etc/auto.master
#create file and add line
sudo echo -n "usbdisk -fstype=auto :/dev/usbdisk1" > /etc/auto.ext-usb
#restart autofs
sudo /etc/init.d/autofs restart

[jefflunt]

Fucking awesome! I'll try it tonight - this is the big piece I'm really excited about.

[brandtdaniels]

created a script to copy the roms (/usr/local/bin/copyroms.sh):

#!/bin/bash
export HOME="/home/pi"
SOURCE="/mnt/usbdisk"
TARGET="/home/pi/roms"
if [ -d "$TARGET" ]; then
   rm -rf $TARGET/*
fi
if [ -d "$SOURCE" ]; then
   find $SOURCE -type f \( -name "*.nes" -o -name "*.NES" -o -name "*.Nes" \) -a \( ! -regex '.*/\..*' \) -exec cp {} $TARGET \; 
   echo "Copied ROMs to $TARGET" >> /var/log/syslog
   killall glint-es && /home/pi/glint-es/glint-es &
else
   echo "ERR: $SOURCE does not exist."   
   exit 1
fi
exit 0

[brandtdaniels]

updated both scripts above...tested and working well...

[jefflunt]

Got this stuff integrated into the wheezy-current branch. Working on getting some requite changes applied in glint-es as well, and then it's off to create a new release.

[jefflunt]

glint-es will now start with an empty game list and prompt the user to insert a USB stick to add games.

I'll close this case when I merge the changes to master.

[brandtdaniels]

Let's do an internal release first amongst all involved in this project before a public release.

[jefflunt]

This has been fully integrated into the latest release.

[jefflunt]

The feedback and other things that get fixed because other people are trying it is too valuable.
