• Handle distributions that do not have /usr/lib directory available (bc988b0)
• booster cat: return an error if the requested file doesn't exist (ab0f6f3)
• generator: Do not rely on user's lookup order for binaries (#213). With this change booster stops using $PATH envvar and instead relies on the predefined list of directories to lookup binaries. It is done for security and reproducibility reasons.
• Add support for *.zstd compressed firmware.
• Detect and handle iso9660 filesystem type #223. Booster can be used for booting from *.iso images now, this gives faster boot and smaller iso images.
