The only reason for checking footer is to get uncompressed data size to keep grub_file_read() happy. Possible sollutions to avoid this: - add size field in stream header and break compatibility with upstream xz/gz, will require forking upstream compression tools or create special tool for crafting upstream created files - increase size while consuming blocks (possible with xz, don't know if with gz), this leaves possibility to get grub_file_read() unhappy - try to guess uncompressed data size based on compressed size -- Szymon K.
