According my revised calculations (this time somewhat based in reality), the NMEA data will come to about 2 megabytes per hour. Not a lot, but when you're talking about 6 weeks of driving, 32 megs won't be enough. On the other hand, assuming I go the path of making a RAM drive for temp storage, even if the RAM drive is only 1 meg in size, that means I'll only need to write to the hard drive every half hour or so (plus right before the script closes). In which case, it doesn't seem like it would be too risky to have the normal data partition set to RW for a couple of seconds every half hour. Does that make sense?
Yes, that makes sense.
As Bitt suggested, you can also simplify handling of the RO/RW status by installing one of mcomb's ext3 enabled Hijack builds (or build it yourself from the standard Hijack source code -- it's just a config option that needs to be enabled). With ext3, the drive could be left mounted RW without much chance of harm, giving less risk of something bad happening should the empeg power down suddenly.
Cheers
