I finally installed NetBSD on my Performa 6360.

But, at the end of installation process and every time the system boots, I get 
messages regarding the file system (/) is full. I first used the default 
value (32 MB) and after that, I raised to 74MB, but the error remains the 
same.

It's not relevant and NetBSD is running well, but I would like to know what 
kind of problem is this.

Thank you for helping.
