Since upgrading to 0.6.2, partitioning my flash disk and running
genunion I am now not only able to make ordinary configuration changes
sticky but the root password too.

The trouble is however that if your mobo only supports a single hard
disk channel, having multiple partitions does not really help. If the rw
partition wears out it might as well all be on the same partition
anyway, as the whole flash module will need changing.

I understand the philosophy often cited in this forum that in reality,
the real lifetime of flash under astlinux could be a very long time, and
you could even take the precaution of swapping flash modules every year
or so.

I think this is a point well made if you are the person maintaining the
system, e.g. you are running your own pbx or are a hobbyist. However
this strategy does not fit well imv once you try and work it into
commercial scenarios and business models.

If I had (say) hundreds of Astlinux boxes in the field, having to send
someone out to each site once every year is certainly not going to be
cost effective.  Neither is the continual disruption and risk of
downtime to the client desirable.  I think trying to pass the burden of
this maintenance on at time of sale to the buyer would also make for an
unattractive option.

I do not have a definitive list of all that is stored on the rw flash
module, but I understand that CDRs and Voicemail are possibly amongst
the noisiest. Wouldn't a better option be to try and store these in RAM
and if necessary support the unit with a UPS ?

Your thoughts please.
