+Hack to pass the full linux-mod-r1 toolchain to make during ./configure.
+Not needed at build time given can pass it normally then.
+
+Eclass has workarounds, compiler/version matching, and its own set of
+user variables which creates disparity between ebuilds if not used.
+
+For the (normal) alternative: KERNEL_{CC,LD} alone is insufficient,
+but combining with KERNEL_LLVM=1 when CC_IS_CLANG will allow it
+to work for *most* people (will likely still need KERNEL_LD from
+linux-mod-r1, or ThinLTO kernels may fail with sandbox violations).
+
+Note KERNEL_* also cause failure if they contain spaces.

+		OpenZFS is an advanced file system and volume manager which was originally developed
+		for Solaris and is now maintained by the OpenZFS community
+
+		It includes the functionality of both traditional file systems and volume manager.
+		It has many advanced features including:
+			* Protection against data corruption. Integrity checking for both data and metadata.
+			* Continuous integrity verification and automatic “self-healing” repair
+			* Data redundancy with mirroring, RAID-Z1/2/3 [and DRAID]
+			* Support for high storage capacities — up to 256 trillion yobibytes (2^128 bytes)
+			* Space-saving with transparent compression using LZ4, GZIP or ZSTD
+			* Hardware-accelerated native encryption
+			* Efficient storage with snapshots and copy-on-write clones
+			* Efficient local or remote replication — send only changed blocks with ZFS send and receive
+
+		The OpenZFS project brings together developers from the Linux, FreeBSD, illumos, MacOS, and Windows platforms.
+		OpenZFS is supported by a wide range of companies.
