Ah yes, silly me, got liblz4-1 confused with liblz4-dev, had to download the 1.9.3 *.deb packages manually cause apt-get is pushing 1.8.3.
Now everything is working top-notch.

Regarding mkfs.erofs, I know it can take file_contexts, but how should we handle fs_config, if it's even necessary?

Maybe "sudo apt install liblz4-dev" for debian.

(Anyway, I may need to add another erofsfuse package for Debian sid,
 I may seek some time to do this.)
