boot loader detection
Hello, I was looking for a way to detect the installed boot loader of an image and I found this: https://github.com/arvidjaar/bootinfoscript This script will inspection a lot of things on a running system and will output a Report. The most interesting part is that it uses known Master and Volume Boot Record byte-patterns to determine the installed boot loader:

Re: boot loader detection
...s some sort of detection like this: # file -bsL /dev/sdb DOS/MBR boot sector; partition 1 : ID=0x83, start-CHS (0x0,32,33), end-CHS (0xce,29,63), startsector 2048, 250067632 sectors, extended partition table (last) Adding it to file means it will be available in libguestfs automatically (via 'guestfs_file' API), and means it would be generally useful to other people as well. However I'm not opposed to adding it to libguestfs if for some reason it's not possible to add this to file.

[PATCH] guestfs_file_arch command
This patch adds a new function, guestfs_file_arch, which is like guestfs_file but specifically intended to determine the architecture of binaries and libraries. Usage is: guestfs_file_arch (g, "/bin/ls") ==> "x86_64" (or whatever) What it can do: - ELF binaries - ELF shared libraries - Windows Win32 and Wi...

[PATCH 0/3] Use __attribute__((cleanup(...)))
This patch series changes a small part of the library to use __attribute__((cleanup(...))) to automatically free memory when pointers go out of the current scope. In general terms this seems to be a small win although you do have to use it carefully. For functions where you can completely get rid of the "exit code paths", it can simplify things. For a good example, see the

[PATCH 0/3] Inspection code in C

[PATCH v2 00/12] Allow APIs to be implemented in OCaml.
Version 1 was here: https://www.redhat.com/archives/libguestfs/2017-June/msg00003.html This patch series reimplements a few more APIs in OCaml, including some very important core APIs like ?list_filesystems? and ?mount?. All the tests pass after this. The selection of APIs that I have moved may look a little random, but in fact they are all APIs consumed by the inspection code (and some more

[PATCH 0/23] factor and const-correctness
This started as a simple warning-elimination change. I'll get back to that series shortly ;-) It turned into a factorization and constification exercise during which I got a taste of ocaml. Thanks to Rich Jones for help with a few snippets in generator.ml. The overall result is that many previously-manually-maintained bits from daemon/*.c functions are now hoisted into the automatically-

[PATCH v3 00/19] Allow APIs to be implemented in OCaml.
v2 was here: https://www.redhat.com/archives/libguestfs/2017-June/msg00008.html This series gets as far as a working (and faster) reimplementation of ‘guestfs_list_filesystems’. I also have another patch series on top of this one which reimplements the inspection APIs inside the daemon, but that needs a bit more work still, since inspection turns out to be a very large piece of code.
