Custom operating system generation for resource-constrained computing systems

A method comprising:

• generating, by a processing device and in a cross-platform runtime environment, a custom operating system for a computing system by:
• generating, by the processing device and based on one or more configuration files, a kernel comprising a plurality of kernel features and a set of baseline packages comprising a plurality of dependencies;
• modifying, by the processing device, the kernel by removing at least one kernel feature of the plurality of kernel features from the kernel;
• and
• modifying, by the processing device, the set of baseline packages by removing at least one dependency of the plurality of dependencies from the set of baseline packages;
• and
• deploying, by the processing device, the custom operating system comprising the modified kernel and the modified set of baseline packages on the computing system.

A non-transitory computer-readable medium comprising instructions that are executable by a processing device for causing the processing device to perform operations comprising:

• generating, in a cross-platform runtime environment, a custom operating system for a computing system by:
• generating, based on one or more configuration files, a kernel comprising a plurality of kernel features and a set of baseline packages comprising a plurality of dependencies;
• modifying the kernel by removing at least one kernel feature of the plurality of kernel features from the kernel;
• and
• modifying the set of baseline packages by removing at least one dependency of the plurality of dependencies from the set of baseline packages;
• and
• deploying the custom operating system comprising the modified kernel and the modified set of baseline packages on the computing system.
