    Good Day –

    Can you point me to references or tell me what areas of the file system are not overwritten by firmware upgrades?

    We’re looking for places to put scripts and other files.

    We have a variety of MTCDT-LAT1, MTCDT-LVW2 and MTCDTIP-LAT1 gateways.

    Thanks in advance for your help.

    There are two partitions that are untouched on upgrade.
    /var/config
    /var/oem

    admin@mtcdt:/var$ sudo df -h

    Using an SD card is another option if more space is needed.

    Details are found in mLinux documentation. AEP is built on mLinux so these low level details also apply.

    A firmware upgrade will overwrite only the kernel and rootfs partitions.

    Hi Jason –

    We have related questions we’re hoping you can help us with:

    (1) Do you know if folks have successfully installed VPN client software on the gateways? We’d really like to have web admin page access for Conduits out in the field.

    (2) I haven’t looked around at where the cron job files are located yet. Do you know if customers are using cron jobs on their Conduits?

    (3) Would the VPN client software and cron jobs survive a firmware upgrade?

    Thanks,
    William

    cron will not survive an upgrade
    A custom app could be used to install them after upgrade.
