Subject: [PATCH 2/2] efivarfs: rework the filesystem to make it human readable
Date: Fri,  3 Mar 2017 16:31:37 +0100	[thread overview]
Message-ID: <1488555097-21189-2-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <1488555097-21189-1-git-send-email-plagnioj@jcrosoft.com>

today we use <varname>-<guid as %pUl>

such as Boot0000-8be4df61-93ca-11d2-aa0d-00e098032b8c

now we will use a different approach where will represent first the vendor
as a directory and then inside the associates variable.

But also create symlink on the vendor with readable name.

so it will look like this:
