Adding Debian packages
General
It's not recommended to duplicate SOM's internal storage/clone from one device to another. There are few scripts run for the first time at startup, and configuration files are generated, which are unique to the SOM. A better approach is to add required packages, services, and applications to the Debian rootfs at compile time using the build script. The resulting rootfs, created by the build script, will then be available as tarball at ~/var_mx8mm_dart_debian_buster/output/rootfs.tar.gz, ready to be deployable for other targets.
Adding packages to rootfs
If you want to add more packages to Debian, you can add your list of packages to the build script, by using the build script variable G_USER_PACKAGES.
For example, if you want to add the packages git and vim:
#### user rootfs packages #### readonly G_USER_PACKAGES=" \ git \ vim \ "
File: ~/var_mx8mm_dart_debian_buster/var_make_debian.sh
and build the rootfs according to the Debian Build Release guide.
Adding application to rootfs
If you have your application to be installed on your rootfs:
Take https://github.com/varigit/debian-var/blob/debian_buster_var01/variscite/weston_rootfs.sh#L295
lines as an example and install your applications, config files / settings etc.
Don't forget to copy your resources to variscite folder.
Build the rootfs
Please refer to the Debian Build Release guide to learn how to use the Debian build script to create the rootfs.
