If we enable 'cryptsetup' PACKAGECONFIG for systemd, there would be circular dependency issue among 'systemd', 'cryptsetup' and 'lvm2'. cryptsetup only needs libdevmapper from lvm2. So we separte libdevmapper into a new recipe to solve this circular dependency issue. Signed-off-by: Chen Qi <Qi.Chen@windriver.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>

Subject: [PATCH] implement libc specific reopen_stream
|
|
|
|
musl defines stdin/stdio/stderr as constant types which means
|
|
we can not assign to them as we are doing here but works ok with glibc
|
|
therefore abstract out the _reopen_stream definition depending upon if
|
|
we are using glibc or otherwise

|
