I got mail from this project titled Einstein@Home needs your help again.
OK. I'll help if you tell me how make it run without the HDD spinning up every couple of minutes. I have latest Debian with 2.6.15.1 kernel and 1 GB RAM.

Set your preferences for 'write to disk no more than once every X minutes' to a large value. Just remember that this is when checkpointing is done. So if you interrupt processsing you'll lose work.

I set disk_interval to 9999999 and HD stand by time to 20 seconds and the HD won't still spin down. noatime mount option has no effect either. I ran the install script in tmpfs so the paths are right.
When I run prime95 torture test from tmpfs with output directed to log file the HD spins down as it should. Same with POV-Ray. Looks like BOINC is designed not to work with ramdisk.
At this point I'm looking for a solution which I can copy & paste into ssh console.
What happens if you set it to

It now works as expected with 2.6.18.1 kernel and official boinc_5.4.9_i686-pc-linux-gnu.
Just install to /tmpfs and run from there:
nohup ./run_client -no_gui_rpc >& /dev/null &
The disk_interval is 120 s.
