I am quite fed up with the instability of my /opt filesystem.
Every time I turn off my N900 I am not sure it will wake up well or with a damaged home partition, and always do a sync and wait until I see no cpu activity to turn off. But this seems not to help.

One of the most dangerous activities is changing the desktop theme: it more then often ends in uncountable errors in /opt.

I must thank Titan's power kernel for its forced fsck on start and RobbieThe1st backupmenu otherwise I would be forced to start over twice weekly, and this is becoming unbearable.

I thought it was swappolube, but the /opt filesystem seems to generate errors either with or without it.

What could I do to get more stability? Thanks in advance
