Have been very happily using libreelec for a couple of years now on my small mediacenter run by a Pi 3. Was very happy so far.
Just now I realized that I could use that Pi also as a file server, storing not only my music and videos, but all pics and documents, and make it available via WiFi to all my devices (right now depending on which device I happen to be, I need to grab an external HD and search for the doc, or store it locally and then copy it eventually).
I wanted to do this with a mirror RAID. If I run this as a file server, then I need redundancy and backups right away.
Unfortunately I realized I'll hit walls with libreelec here - can't install mdadm with apt-get, and also couldn't find any add-on.
So currently I am thinking of installing some other OS on the Pi and set it up that way (hint: if someone has a suggestion on how to achieve my goal without reinstalling the OS and keeping libreelec, I am all ears).
Is it possible to just backup the kodi configs and install them on the new OS afterwards and have a possibly smooth migration (I am anticipating version issue, but that's a different story)?
