Rationale
Karmic is out, with the new ext4 filesystem. Which settings benefit a ssd drive? None at the moment, the user have to tune several things by hand and run in open bugs at lauchpad while doing this. Lots of wiki pages are available but most of them did not run cause of karmic structure changes.
/var/log
/tmp
/var/tmp
as tmpfs ramdisk in memory.
Reduce logging to single adhoc file in tmpfs, without logrotate or save all in a batch to disk at shutdown. A simple netbook is not a server so noone need tons of logfiles for forensics.
Set swappiness, noatime, io-scheduler, filesystem tweaks in proper places.
So we can benefit from a faster and long living ssd.
This is an excellent point... SSD's are fast coming into the mobile market and many of us are purchasing them for the longer battery life AND the speed... having a recommendation for automatically tweaking the install when ubuntu detects an SSD would make us one more step ahead.
At the moment most tiny computers comes with a ssd boards with controller that fake a harddrive. They use raid, wear levelling and some firmwares do defrag when idle. Yes we need something like logfs for real flashdrives and sticks at ubuntu setup. But on real ssd drives with controller and buffer we have to reduce unnecessary write cycles.
Netbooks comes with 1gb of ram caused by m$ license politics. Typical UNR needs around 170mb of ram, noone runs big servers on them so much ram is free available to store temporary files. These files goes lost at powerdown and no further service for cleaning up /tmp must be applied.
