[Trash_Can_Man]

Im planning to move my actual build to a librelec build with dockers (im actually using an ubuntu minimal with dockers) because i would also like to use the box as a tv box, in my actual build in the base system i only have installed webmin, docker, samba and mc (mostly to do stuff over ssh easily), would i be able to use these apps or any of them have any special restriction in comparison to using them on an ubuntu minimal? (mostly my guess is that both mc and docker work without problems, but what about webmin and samba?)
Second question, i usually prefer to keep config and data files on the external hdd, most dockers allow to move config and data files, but i prefer to move also the docker images and containers outside, to do this the prefered docker method is to create a file:

Code:

systemctl stop docker
sudo nano /etc/docker/daemon.json

with only this:

Code:

{
 "graph": "/shared/config/docker"
}

where "shared/config/docker" is my prefered place (its a symlink to the external hdd, im guessing that symlinks also work without issues, right?). After a system or service restart docker stores his stuff on that folder. Would i be able to set it this way on your librelec image?

BTW this would be on a rock64 4gb

TLDR: can i use samba, symlinks, webmin, mc and can i move the docker files using your libreelec distro?

PS: also, what version of docker images should i use with this build? armhf or aarch64/arm64?
