Thanks Lonnie great explanation and I have also enabled persistent log.
The reason that I asked this question is that I am considering performing
verbose logging for Asterisk which will be handy for troubleshooting.
I would probably prefer logging to be on tmpfs to reduce writes to flash but I
found that losing the logs on reboot was very annoying if I was trying to
troubleshoot issues that caused a reboot.
As all my systems now have an SLC CF or 16G or greater mSATA maybe I'm worrying
too much about flash writes.

have a /mnt/kd/ symlink. Well, these programs are standalone and do not
require a service init.d script, as such there is no script to symlink /etc/foo
-> /mnt/kd/foo. AstLinux could create dummy service init.d scripts for these
cases, but chose not to and allow users to simply edit the /etc/ config files
directly. Additionally, many users will never have the need to edit these
files.

Of course I enabled "PERSISTLOG=yes" in my user.conf :-).
