    Space requirements

    As mentioned above, emteria.OS consists of multiple separate packages, which are automatically downloaded and installed to your SD card or the device’s internal memory. The size of those packages can vary depending on the device and emteria.OS version. The installer will use the full data storage and partition it accordingly. Here is an example of approximate partition sizes created by emteria.OS 11.3.0 on a 16 GB SD card for Raspberry Pi 4 (these values may change in future releases):

    Partition Size Comment
    boot 64 MB Chosen to be as small as reasonably possible
    system 2.1 GB System data and reserved space of about 1 GB each
    oem 512 MB Space for pre-installed business extensions
    odm 512 MB Contains original design manufacturer (ODM) customizations
    misc 256 MB The recovery partition of the system
    cache 512 MB Contains most of the temporary files and logs from your device
    vendor 256 MB This partition contains any binary that isn’t distributable to AOSP
    userdata 8.6 GB This partition contains the user’s data (such as settings, contacts, messages and your apps)
