I have been seriously considering using ext2 on the SD drive. Afterall, it will have /usr on it and not a lot of activity happens to files in /usr (or am I missing something?). I figure to run the check program (I'd have to research that again) after yum updates... I have mixed feelings about ext2 for the SSD drive that would have the rest of the / tree. adding 'noatime' (and NOT misspelling it this time!) is a big win. Also need to look into nodiratime, seems it goes with noatime.

In that case, do you have a USB stick w/ 1GB of free space? How about a live system installed to it? That should let you mount your / filesystem and repair fstab..
