Hi David,
A hot tip would be to configure either syslog to log to a logserver
or at least mount a tmpfs filesystem on /var/log.
Running a syslog could wear out the flash quite quickly, especially
during the development phases...
While you are at it, mount tmpfs's on /tmp and /var as well.
I believe JFFS2 suits very well in a embedded device, the system
just need to be configured for a such, since a "standard" linux
installation are more outlined for server/desktop usage ;-)
Regards,
Per
