System is running ok, reboots ok etc. just concern that Ram is no-longer used and SD card being used instead (eventually leading to failure/corruption/performance degrade of SD). Please comment if dietpi-ramdisk is now obsolete and what replaced it if so. thanks for all your support :)

Hi,

many thanks for your report. If I'm not mistaken this can be ignored. Isn't it @MichaIng

maybe similar to this?? #3532 (comment)
Because scripts moved from /DietPi > /boot ??

[MichaIng]

Many thanks for your report.

First of all: Yes DietPi-RAMdisk has been removed. This included only the /boot/dietpi.txt, /boot/dietpi and /boot/config.txt on RPi. The SD writes are likely lower now since in the past, the whole RAMdisk content was written to disk on every reboot and after every update (as it was attempted on your case), now only when one actually changes a setting, the single config file is written. But it depends a bid und usage of course. The main purpose of the RAMdisk was not to reduce SD writes (those are minimal for config files) but to speed up SD reads, i.e. DietPi scripts and settings, and this is now assured via vmtouch service, which keeps those files locked in native file system (read-)cache. The reason for this was to simplify our boot and shutdown process (no need to copy back and forth the RAMdisk content) and to eliminate the risk that a system crash or unclean shutdown leads to lost config changes and in case broken/reverted updates. So it should be all more solid now.

And yes, we had this update issue one or two times before, which occurred because the updater somehow did not kill itself (more precisely, its parent script) as intended and I am still now sure how this can happen EDIT: it has been fixed meanwhile, lol forgot that we found the reason and fixed it already 😄. But as Joulinar said, it can be ignored since the updater already finished. It is an obsolete parent process which should have been killed but wasn't and now finished with outdated post-update steps, e.g. writing the RAMdisk content to disk which is not required and obviously not possible anymore.

But just to be very sure, do you still have the updater log in terminal, or the related log file:

cat /var/tmp/dietpi/logs/dietpi-update.log

---

Ah yes all makes sense, the v6.25-only bug where I moved the output split for log file into a pipe, but the pipe input processes looses control over the parent shell, hence cannot kill it anymore. Learning never ends 😄.

Thanks for the timely and informative post! The situation is exactly as you describe and the installer did complete successfully. I'll paste the log FYI in any case. thanks again.

Okay, great, everything is fine then. Luckily there are not much systems on v6.25 anymore, since a reliable fix on a 6.25 system prior to the update is not reliably possible. We could hack something inside via MOTD but not everyone has it enabled.
