[arm-allstar] SD Card full will no write anything

[Danny K5CG]

Yes you are 100% correct David. I mispoke and actually found this out myself the other day because Supermon would not display callsigns from astdb.txt which is also on the tempfs filesystem in RAM. the astdb update juob could not build a file because /var/log/asterisk was full. That's what led me to the YUGE btmp and btmp.1 files in /var/log.

Rebooting solves it but if you are running a hub for a club and there are users who stay connected, I'd rather not do that.
