NAND Write operations

[Sameer Naik]

Hi,
This may not be the right place to ask this question, but i only ask
this because i believe most of the developers on this list work
primarily with embedded systems. So here goes it.

Normally on a linux system network configuration related files like
resolv.conf and ifcfg-eth*, etc are stored in the /etc folder. These
files are normally updated at boot or precisely when the network is
configured. NAND memory have a ~100K write cycles before which write
could start failing.
This number is rather very large, hypothetically even if the network
is configured 10 times a day the flash is good for around 27 years
(100000 / (365 * 10)).

Secondly, considerable amount of fragmentation could occur due to
small updates on the file system

I may be getting a little paranoid here, but how much is this of
cencern on a production system.
