not all changes to rc.local are kept

Question

not all changes to rc.local are kept

jgeisler0303 opened this issue 5 years ago · comments

Hi and thanks for this wonderful image!
I got it working and when I edit rc.local e.g. to comment out the launch of mpd and do save_change this is kept after the next reboot. But when I change /opt/eth.disable to /opt/eth.on this change seems to be magically be undone.
I would really like to enable wired Ethernet. Can you help me?

Hi, I solved the problem myself: there is no "magical" strange behavior. Instead, save_changes seems to not always write the changes to the SD card. Maybe there is some buffer and flushing this buffer is delayed. In any case, calling save_changestwice or even three time and/or waiting some time before reboot helped and all changes persisted.

Hi and thanks for the reply. The problem is still actual but almost never problematic anymore since I do the triple save_changes plus a reboot.
I will try you suggestions and observe different sd cards. But probably will not be gathering much intel soon since my device is now running headless as intended.

never watch any problem for spi flash, only for some unbranded sd
