#6480 is fixed as of yesterday, should be in next joyride. I'll be re-doing Nokia's patches so that they go upstream if we still want them after 8.2 is out; however, I don't think the approach used by them actually helps us. We already have a very limited amount of storage space and reserving space for the root user just reduces what the end user can actually use. I think analyzing performance of non-JFFS2 file systems and picking a replacement should be a high-priority item for 9.1 update. ~Deepak -- Deepak Saxena <[EMAIL PROTECTED]> _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
