<div class="">Well, remember, we are dealing with flash RAM here.
After enough write/erase cycles, it *will* wear out. The goal is
to optimize the overall system to get maximum lifetime out of
the media. For example, on our production setups we do things
like putting ‘/var/log’ on tmpfs (it doesn’t matter for the
particular application that the log data evaporates after
reboots). That greatly reduces wear on the media, while still
allowing log data to be accessed during a session for debug
purposes.<br>

All too often I am looking at contents of /var/log after a system
restart to figure out what went wrong.<br>
<br>
So that is yet another reason I am sticking with SOCs that have good
sata support. So I can run rootfs there...<br>
