Subject: [PATCH] multipathd: replace libreadline with libedit
|
|
|
|
Linking multipathd with libreadline may cause a license conflict,
|
|
because libreadline is licensed under GPL-3.0-or-later, and
|
|
libmultipath contains several files under GPL-2.0.
|
|
|
|
See:
|
|
https://github.com/opensvc/multipath-tools/issues/36
|
|
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=979095
|
|
https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility
|
|
|
|
Replace the readline functionality with libedit, which comes under
|
|
a BSD license. The readline library can still be enabled (e.g. for
|
|
binaries not intended to be distributed) by running
|
|
"make READLINE=libreadline".
