7 years ago you can simple move it to the SD card, just find out this line in thermeq3.py:
self.bridge_file = "/root/" + self.devname + ".bridge"
and change to path you need.

7 years ago Yes I know but I'm talking about "general solution" (without needs to change code after upgrade). Maybe it's enough to make a symbolic link. How long are you running your software on Yun? Have you ever problems with errors on internal flash?

7 years ago just from the beginning of the project, its about 3 years? Where is the /var/log stored? Logs are heavily modified files, if logs are stored on internal flash, so I don't expect problems with /root directory. Am I wrong?

7 years ago Are you sure about logs: root@Arduino:~# ls -l /var/log/ -rw-r--r-- 1 root root 0 Dec 11 20:32 lastlog -rw-r--r-- 1 root root 0 Dec 11 20:32 wtmp ? (fresh Yun install just thermeq3 software)

External storage on the Yún You're discouraged from using the Yún's built-in non-volatile memory, because it has a limited number of writes.

7 years ago Maybe it's better to put it on tmpfs (/tmp) and save "backup" at SD card?

7 years ago I I've made a symlink but it's also possible move whole / filesystem on SD card: https://bitbucket.org/unitn/yuntricks/wiki/Setup%20Overlay%20filesystem
Is it a good idea to save thermeq3.bridge file on internal flash? It has "limited" number of writes (probably there is no anti wearing controller on Yun). Maybe it should be a) moved to SD card b) "saved in memory" at from time to time synced to other media (SD card?)
