Centralize variable substitution A bunch of places need to edit files to incorporate the configured paths i.e. bindir, sbindir etc. Move this logic into a common file. Create arc_summary by copying arc_summary[23] as appropriate at build time instead of install time.

Support parallel build trees (VPATH builds) Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

fix booting via dracut generated initramfs Dracut and Systemd updated how they integrate with each other, because of this our current integrations stopped working (around the time 4.1.13 came out). This patch addresses that issue and gets us booting again. Thanks to @Rudd-O for doing the work to get dracut working again and letting me submit this on his behalf.

Run zfs load-key if needed in dracut 'zfs load-key -a' will only be called if needed. If a dataset not needed for boot does not have its key loaded (home directories for example) boot can still continue. zfs:AUTO was not working via dracut, so we still need the generator script to do its thing.

Properly use the Dracut cleanup hook to order pool shutdown When Dracut starts up, it needs to determine whether a pool will remain "hanging open" before the system shuts off. In such a case, then the code to clean up the pool (using the previous export -F work) must be invoked. Since Dracut has had a recent change that makes mount-zfs.sh simply not run when the root dataset is already mounted, we must use the cleanup hook to order Dracut to do shutdown cleanup. Important note: this code will not accomplish its stated goal until this bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432 That bug impacts more than just ZFS. It impacts LUKS, dmraid, and unmount during poweroff. It is a Fedora-wide bug.

contrib: dracut: fix race with root=zfs:dset when necessities required This had always worked in my testing, but a user on hardware reported this to happen 100%, and I reproduced it once with cold VM host caches. dracut-zfs-generator runs as a systemd generator, i.e. at Some Relatively Early Time; if root= is a fixed dataset, it tries to "solve [necessities] statically at generation time". If by that point zfs-import.target hasn't popped (because the import is taking a non-negligible amount of time for whatever reason), it'll see no children for the root datase, and as such generate no mounts. This has never had any right to work. No-one caught this earlier because it's just that much more convenient to have root=zfs:AUTO, which orders itself properly. To fix this, always run zfs-nonroot-necessities.service; this additionally simplifies the implementation by: * making BOOTFS from zfs-env-bootfs.service be the real, canonical, root dataset name, not just "whatever the first bootfs is", and only set it if we're ZFS-booting * zfs-{rollback,snapshot}-bootfs.service can use this instead of re-implementing it * having zfs-env-bootfs.service also set BOOTFSFLAGS * this means the sysroot.mount drop-in can be fixed text * zfs-nonroot-necessities.service can also be constant and always enabled, because it's conditioned on BOOTFS being set There is no longer any code generated at run-time (the sysroot.mount drop-in is an unavoidable gratuitous cp). The flow of BOOTFS{,FLAGS} from zfs-env-bootfs.service to sysroot.mount is not noted explicitly in dracut.zfs(7), because (a) at some point it's just visual noise and (b) it's already ordered via d-p-m.s from z-i.t.
