The primary motivation to relicense is a desire to integrate with projects
that are licensed under the Apache License version 2.0. Although opinions
vary, there are some who argue the the LGPL-2.1 and Apache-2.0 licenses
are not fully compatible. We would like to avoid the ambiguity and
potential for controversy.
Projects we would like to consume that are Apache-2.0 licensed include
Seastar, OpenSSL (which is in the process of relicensing to Apache-2.0),
and Swagger (swagger.io). Note that some of these are dynamically linked
or consumed via a high-level language and may or may not require a change
to LGPL-3.0, but providing the option for LGPL-3.0 certainly avoids any
uncertainty.
A few other source files are already incorporated into Ceph that claim an
Apache-2.0 license:
src/common/deleter.h
src/common/sstring.h
src/include/cpp-btree
The Ceph developers would further like to provide a license option that is
more modern than the current LGPL-2.1. LGPL-3.0 includes updated,
clarified language around several issues and is widely considered
more modern, superior license.

The license applicable to the files under doc/ was originally declared (in the
top-level file COPYING) to be "Creative Commons Attribution-ShareAlike (CC
BY-SA)" by ed0653b493
This license declaration omitted a version number.
Some time later ef7418421b was merged, mentioning
CC-BY-SA-1.0 as one of the Ceph source code licenses. Although the purpose of that
commit was only to summarize the canonical license information from COPYING, it
unintentionally became the only place in the source code where the doc license
version was specified.
In March 2018, the Debian project warned that CC-BY-SA-1.0 does not meet its
criteria for inclusion in the "free" section of the Debian distribution. (For
that, at least version 3.0 must be used.)
This new commit removes the doc license ambiguity by setting it to CC-BY-SA-3.0
in all places where the license is mentioned.
The exact spelling of the license name is taken from https://spdx.org/licenses/

The commands in README.md are aligned using one tab or eight spaces,
the github markdown engine not handle this properly, so using one tab
universely.

install-deps.sh installs the dependencies based on the content of
debian/control (if apt-get is found) or ceph.spec.in (if yum is
found). The manually maintained list of dependencies for deb based
operating systems (deps.deb.txt) and rpm based operating
systems (deps.rpm.txt) are deprecated.
