[FHS] Make zfs instal fhs compatible

[alexxy]

zfs and spl packages should be fhs compatible.

[behlendorf]

Exactly which files do you believe are not FHS compliant? Just the zfs, zpool, and libraries. You can can set --prefix=/ to ensure they are installed in the primary hierarchy. By default configure assumes /usr/local/ and most rpms/debs assume /usr. But you can absolutely override this.

./configure --prefix=/
make
make install

[alexxy]

Yeah. But if you do so you will get /libexec /includes and so on. Also udev helpers should be placed under /lib/udev and many other things are fhs incompatible. They may be acceptable on solaris but not on linux. I can make a patch to fix this.

[dajhorn]

Things installed to /lib/udev should be managed by the packaging system. Installing to /etc/udev is probably the best default for a local install.

I resolved the libexec violation in dajhorn/pkg-zfs@9d8c292 and dajhorn/pkg-zfs@5d633c8 for Debian and Ubuntu. However, per earlier discussion, moving the libexec scripts into a zfs-test package could be an improvement.

[alexxy]

I mean binaryes that called from udev rules such as zvol_id and friends. They should go to /lib/udev since they are udev helpers

[dajhorn]

Yes, right. I will apply this change to the deb packaging.

[alexxy]

I think i'll create patch for zfs build system so it will install all things in fhs compatible way

[behlendorf]

If you can propose a patch which identifies all the files which are not FHS compliant that's a good starting point. However, I want to ensure that we don't start hard coding any install paths. This probably means splitting off a zfs-test package. This would allow the core utilities/libraries/helpers to be installed in the primary hierarchy with just a --prefix=/. Everything which belongs in the secondary hierarchy which is largely zfs-test could then be configured with --prefix=/usr.

[behlendorf]

The provided rpm/deb packaging in master has been updated to install the zfs utilities and helpers in fhs compatible locations.
