hmmm - this is really interesting, you can stick syslogs and /tmp and /var/tmp in tmpfs just by editing fstab ? Cool. I did this in a vagrant vm and it's making systemd rather unhappy, although the system seems to run ok: - initial login after bootup is 'very' slow - systemctl reports user@MYUID.service failed - systemctl reports systemd-update-utmp.service failed - systemctl reports 'Failed to start System Logging Service' every 90 secs or so - systemctl reports watchdog timeout for systemd.logind - systemctl reports watchdog timeout for systemd.journald I did a little more research with some controlled reboots and found that systemd really doesn't like /var/run in tmpfs. - not putting /var/run into tmpfs made the problems above go away, and 'systemctl' is clean Does a 'systemctl' command on your system show a couple failed processes ? tmpfs /var/www/weewx tmpfs defaults,nosuid,mode=0755,nodev,noatime > 0 0 > tmpfs /var/log/nginx tmpfs > defaults,nosuid,mode=0755,nodev,noatime 0 0 > - for the weewx directory, your NOAA reports will disappear every time you reboot, so wouldn't weewx (very slowly) regenerate them every reboot ? - I didn't notice where your archive directories are located. Do you copy the old one back into place via rc.local or something on every reboot ? Cool idea putting that stuff in tmpfs rather than hard-allocating a ramdisk and maybe not using it...that'll give me more free space on the pi that does my weathercam.
