New feature, improvement proposal

with simplified reproducible env description, where OS type is described from newline, no need to do anything

# effective build environment information (simplified for reproducibility)
java.version=11
os.name=Unix or Windows

but when full os.name is kept (non-reproducible buildinfo), storing line.separator can be useful,
as sometimes we can use Linux but emulating Windows by defining line.separator.

we can have:

# effective build environment information
java.version=11.0.27
java.vendor=Ubuntu
os.name=Linux
os.version=...
os.arch=...
line.separator=\r\n
