BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file

VMWare Workstation 8, 9, and 10 support booting to a UEFI environment. Create a new virtual machine Open the .VMX file of your virtual machine in Notepad (or similar) and add the following line to it: firmware="efi" Save the .VMX file.         In addition, order to be able to select network boot, it is advisable to add a boot delay to the startup of the virtual machine. This can be done by adding the line "bios.bootdelay = 5000" (time is in milliseconds)
