It calls initramfs_load_file() directly, this loads the file exactly once into memory. Going through a Lua string loads the file, then copies it into a (interned) Lua string, then copies this string again in initramfs:add_file(). This doubles the peak memory usage (might even triple it if you are not freeing the file before p...

From: Paul Emmerich <p.emmerich at first-colo.net> Hi, the new API for initramfs and files in master lacked the ability to build initramfs objects from files loaded via HTTP/TFTP in Lua. The documentation indicated that it should be possible (and I believe I did that in an older version). I implemented a few new functions to handle files/initramfs objects better. Changes: * NEW:

...nd just pointing into the Lua memory representation makes a lot more sense. [f]loadfile() is "smart" in the sense that if, and only if, the size of the file is known ahead of time it allocates the buffer in one shot, rather than using realloc(). Do note that [f]loadfile() (as opposed to initramfs_load_file()) just loads data into a memory buffer. If there is a way to represent a memory buffer allocated by C as a Lua string that would pretty much take care of the same thing. floadfile() even allows a chunk of data to be prepended to the buffer, which could be useful in the case of a Lua string needi...
