Hi!! Does enaybody know if there is any way to backup a file from the old rootfs when preforming a system update?
Let’s say I want to keep a log file and keep appending data to it once the update is completed and the system has boot from the new partition.
Apreciate any help or idea as workaroung.
This can be done via state scripts, you can essentially ship arbitrary pre- and post-installation logic along your artefact.
So, if I have log.txt and the current boot partiion is p1 (And the next would be p2, since we are mounting p3 on /data)
where should I back up that file?
if booting from p1 it goes to p2 and viceversa?
@sd-ricardo the only persistent thing is
/data - unless you added more persistent partitions manually. So there it needs to go.
