I have some lab machines which I would like to run E@H during their "downtime". I would prefer using a LiveCD, just to keep things easily maintained. Is there anywhere or anyone who has created a script to make a LiveCD that will boot up and run boinc with your own account details.
such things just should not be writ so please destroy this if you wish to live 'tis better in ignorance to dwell than to go screaming into the abyss worse than hell

Customized LiveCD for E@H

Seems to me the issue with this is that when you turn the machine off there will be lost work. I wonder what ratio of successfully crunched WU to abandoned WU is considered acceptable?
To avoid this issue, in my opinion a better solution would be a live USB key, that uploads into memory at boot time, and downloads the /BOINC directory back onto the USB drive when you do a system halt.
I don't know if either suggestion exists, and would also like to know of any approaches to this

Since USB keys look like a HD to the system. In theory Boinc could be installed on the computer using the USB as the installation drive. All that would be required is to shutdown Boinc before pulling the key to make sure the file in memory are written to the drive.
I'm not sure exactly what is written to the registry, and I believe the WU would have to be UL/DL from the computer crunching it.
Another problem may arise because of the intensive write to disk. A USB key does have a finite number of writes before it goes bad. Again, I am not sure in what range that number might be.
Questions? Answers are in the BOINC Wiki.

The machines would be running long enough(weeks at a time) where it would be worth it, even if you lose a few WU's at the end.
I am sure I could probably make my own LiveCD based off of gentoo's, but I was hoping it had been done before, so I don't have to go through it. :)

If anyone makes this live distro, put me on the mailing list.
I would humbly suggest Debian, and there is a LOT of information on making distros on the Ubuntu website. Thx.

IF the machines are fast enough, and the changeover known a reasonable time in advance, simply keeping thier connect to server time very short and manually disabling get new work could avoid any data loss.

Here's what I've done with the Windows version: Install BOINC and get it set up, then exit BOINC and copy the BOINC folder to flash media (USB drive, CompactFlash, SD card, etc.). Uninstall BOINC and delete the folder from the hard drive. Then, just run boincmgr.exe from the folder on the flash media or move the BOINC folder to a hard drive, temporarily, and back to the flash media later. It always picks up where it left off, even if it's running on a new computer each time. It always seems to know where the data is.

try slax - they even have a boinc module that can be easily slipstreamed into the cd .iso.
