Dear Daniel, Thank you for offering your help, you motivated me to look into this. I would like to ask, where is the libgcrypt source code bundled with grub from? I checked that the files are not from the libgcrypt repository in <git://git.gnupg.org/libgcrypt.git>. My method was to search for the sha-1 sums with `git rev-list` and `git rev-parse`. I automated the task by writing a python script which I called "gitsearchdigest" (you can grab it from <https://github.com/createyourpersonalaccount/gitsearchdigest>.) What I did was run this command: cd grub-core/lib/libgcrypt/src find . -print0 | gitsearchdigest -C /path/to/libgcrypt_repo However it came out blank, which, if my script is correct, means that the files under grub-core/lib/libgcrypt/src do not ever appear in their exact form in the git repository of libgcrypt. I made a manual visual check on ChangeLog-2011 and it appeared to be modified. Thus my conclusion is that grub has files that never appeared in the libgcrypt repository, and it makes my attempt to upgrade it much harder unless I can find out where they came from.
