[arm-allstar] System logs retention

[David McGough]

Hi Mark,

As you know, HamVoIP was setup to minimize writes to the SD card,
attempting to maximize SD card lifespan.

In retrospect, this concern may have been unwarranted.  I've got many
systems in use for years (5+) which perform frequent SD card writes and
still have not had a single actual SD card failure....I have seen
corrupted root (ext4) filesystems a few times, which once repaired
(fsck.ext4) were again fully usable. In the case where the filesystems got
corrupted, the RPi units had crashed hard due to power problems.  I
suspect that most of the reported "bad SD cards" are probably just
filesystem corruption.

Anyhow, there are 2 primary places where log files get written in HamVoIP:  
The /var/log and /run/log/journal folders, both being volatile tmpfs (RAM
drive) filesystems.

Are you wanting to preserve the log contents on the SD card proper, or on 
an external device (e.g.: USB SSD, USB thumbdrive, NAS) ??
