[gentoo-user] ZFS wiki confusion

[Douglas J Hunley]

Anyone got ZFS working on their Gentoo install? I'm contemplating it, but
the wiki[1] confuses me a bit. Specifically, section '3 Installing into the
kernel directory (for static installs)' states:
This will generate the needed files, and copy them into the kernel sources
directory.
root # (cd /var/tmp/portage/sys-kernel/spl-9999/work/spl-9999 &&
./copy-builtin /usr/src/linux)
root # (cd /var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/ &&
./copy-builtin /usr/src/linux)
After this, you just need to edit the kernel config to enable CONFIG_SPL
and CONFIG_ZFS and emerge the zfs binaries.
root # mkdir -p /etc/portage/profile
root # echo 'sys-fs/zfs -kernel-builtin' >>
/etc/portage/profile/package.use.mask
root # echo 'sys-fs/zfs kernel-builtin' >> /etc/portage/package.use
root # emerge -1v sys-fs/zfs
The echo's only need to be run once, but the emerge needs to be run every
time you install a new version of zfs.

Do you really need to copy the files into the kernel tree? WTD is a 'static
install' in this context?

'emerge zfs' shows:
Calculating dependencies... done!
[ebuild  N     ] sys-fs/zfs-0.6.1  USE="rootfs -custom-cflags
(-kernel-builtin) -static-libs -test-suite" 1,500 kB
[ebuild  N     ]  sys-fs/zfs-kmod-0.6.1  USE="rootfs -custom-cflags -debug"
0 kB
[ebuild  N     ]   sys-kernel/spl-0.6.1  USE="-custom-cflags -debug
-debug-log" 209 kB

which seems to pull in the daemon and the kmod so wouldn't the zfs-kmod
ebuild build against the current kernel and drop in the modules directory
all by itself much like any of the 100s of FUSE modules do?

Any clarification on the install process would be appreciated.
