Subject: bug#41855: [PATCH 2/2] hurd-boot: Use 'setxattr' instead of invoking settrans.

From: "Jan (janneke) Nieuwenhuizen" <[email-masked]>
Date: Sun, 14 Jun 2020 18:56:49 +0200

Note: Using `getxattr' on the Hurd instead of running showtrans does not
work (yet?).

* gnu/build/hurd-boot.scm (setup-translator): Use 'setxattr' instead of
invoking settrans.
* gnu/system.scm (hurd-multiboot-modules): Add --x-xattr-translator-records to
enable xattr-embebbing of translators.
