Reduced operating system with Linux kernel on USB flash drive
Struziaková, Lada ; Slavíček, Karel (oponent) ; Komosný, Dan (vedoucí práce)
My aim of the bachelor thesis is to create a modified Linux operating system based on the Debian distribution. Predefined applications, including a local PDF viewer and a web browser, are among its requirements. The entire system is stored on a portable storage device, such as a USB flash drive, and operates in read-only mode. This mode ensures that any changes made while the system is running are erased with the system reboot, except for data stored in the users’ home directories. The remaining unused space on the storage device is reserved for an encrypted partition that serves as a se cure storage for user data created. The assignment of the work was fulfilled using the functions of the live-build system library and the procedure to create a “from-scratch” distribution. Modifications were made to bootloaders, setting up internal system ser vices, creating a script to set up the system using the live-build library, implementing persistence, and other changes. Although the thesis is written in English, the system is prepared for Czech-speaking users. The created configuration scripts and generated ISO images are published under the MIT license available on the GitHub platform.
