- In older systems without sysroot.mount, import before dracut-mount, and re-enable old dracut mount hook - rootflags MUST be present even if the administrator neglected to specify it explicitly - Check that mount.zfs exists in sbindir - Remove awk and head as (now unused) requirements, add grep, and install the right mount.zfs - Eliminate one use of grep in Dracut - Use a more accurate grepping statement to identify zfsutil in rootflags - Ensure that pooldev is nonempty - Properly handle /dev/sd* devices and more - Use new -P to get list of zpool devices - Bail out of the generator when zfs:AUTO is on the root command line - Ignore errors from systemctl trying to load sysroot.mount, we only care about the output - Determine which one is the correct initqueuedir at run time. - Add a compatibility getargbool for our detection / setup script. - Update dracut .gitignore files Signed-off-by: <Matthew Thode mthode@mthode.org> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #4558 Closes #4562
