dracut: use /bin/sh instead of bash as the intepreter Despite that dracut has a hard dependency on bash, its modules doesn't, dracut only has a hard dependency on bash for module-setup (on a fully usable machine). Inside initramfs, dracut allows users choose from a list of handful other shells, e.g. bash, busybox, dash, mkfsh. In fact, my local machine's initramfs is being built with dash, and it's functional for a very long time. Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also allows our users to have that right, too. Let's fix the problem 'make checkbashisms' reported and allows our users to have that right, again. For 'plymouth' case, let's simply run the command inside the if instead of checking for the existence of command before running it, because the status is also failture if plymouth is unavailable. While we're at it, let's remove an unnecessary fork for grep in zfs-generator.sh.in and its following complicated 'if elif fi' with a simple 'case ... esac'. To support this change, also exclude 90zfs from "make checkbashisms" because the current CI infrastructure ships an old version of "checkbashisms", which complains about "command -v", while the current latest "checkbashisms" thinks it's fine. In the near future, we can revert that change to "Makefile.am" when CI infrastructure is updated. Reviewed-by: Gabriel A.

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.
