ok I got everything up and working but I have 1 small issue
when I login tot he gui and try to configure my application its not
outputting files and writing to the database because the sysem is in ro,
how do I make it so my apps data can always be saved ?
is there a special switch ?
remember there is a limited number of writes to flash memory.
You could tell the system to remountrw on every boot, but that decreases
security and increases the speed at which your limited flash writes will
get exhausted.
Look at the mailing list archives for "voyage-sync"
There are hooks in this startup and shutdown script to write the data to
flash infrequently (on bootup/shutdown). and you could add a cron job
to make it sync daily, to limit how quickly you exhaust your limited
flash writes.
frequency depends on how much data you're willing to lose to a server
crash/power outage.
Note that if it's a real database, you'll have to either dump or shut
down the database first.

what about puting the os on the dom and the data goes on a thumbdrive
how would I make it sync the data onto the drive to the dom so there is
a backup to reload if needed
?
