Each Linux system is self-contained in a single file, IMAGE.0, and the previous version of it is kept as a backup IMAGE.0.zs-old.
This file allows znx to rollback to a previous state if the new one doesn't work.
User data is kept in the folder DATA and is stored on the device using OverlayFS. Using the GRUB parameter ZNX_OVERLAYS the user can define which folders are put in the overlay.
[Notice Regarding the Transfer of the mstdn.jp / mastodon.cloud Services] We have received several inquiries showing interest in a transfer following the announcement of the end of the mstdn.jp and mastodon.cloud services.
