The Linux Application Summit (LAS) 2025, a global event dedicated to the development of the Linux application ecosystem, was recently held in Albania. As a premier platform for collaboration among developers, designers, and open-source community leaders, LAS aims to accelerate the full lifecycle of Linux applications - from development and packaging to distribution and user experience.

At the summit, Shuoqi Yu, maintainer of the Kaiming SIG in the openKylin community, delivered a keynote titled "Technical Exploration of the Kaiming Package Format in openKylin." The talk provided an in-depth overview of the Kaiming format’s technical architecture and open-source implementation practices, drawing attention from developers and ecosystem partners worldwide.

Breaking Through with the Kaiming Format

Developed by the openKylin community as a next-generation solution, the Kaiming Package Format introduces several technical innovations:

● Layered Runtime Architecture:

Built on Ostree to enable versioned baseline systems, and integrated with the crun container engine for application-level resource isolation.

● Progressive Security Strategy:

Implements comprehensive lifecycle control - from installation to runtime - through a tri-layered mechanism of namespace isolation, Cgroup resource quotas, and D-Bus communication proxying.

● Developer-Friendly Design:

Offers a visual packaging toolchain and maintains compatibility with the existing .deb package ecosystem, reducing migration costs.

Collaborating on the Future of Open Source

During the technical exchange sessions, Shuoqi engaged in discussions with global open-source leaders, including Aleix Pol Gonzalez, President of KDE e.V. A live demonstration of key features of the Kaiming format - such as resource allocation via Cgroups - gave attendees a hands-on understanding of the package format’s capabilities. The session also facilitated cross-border dialogue on related technologies and practices.
