Remove lines that contain only a hyphen (match '^-$' instead of '-').

I had a root fs with a hyphen in the name (fedora/ROOT/Fedora20-Dev), it was not detected because sed eliminated that line of output from 'zpool list -Ho bootfs'.

Would also like to improve the zpool import behavior.
For autodetecting the bootfs property, it might be good to do 'zpool import -ad /dev/disk/by-partuuid; zpool import -ad /dev/disk/by-partlabel; zpool import -ad /dev/disk/by-uuid; zpool import -ad /dev/disk/by-label; zpool import -ad /dev/disk/by-id; zpool import -ad /dev'.
If there's a more efficient way to handle this, I'm open to suggestions.
I have two pools on separate GPT partitions, the default import behavior locates them in /dev/disk/by-id and cannot import one of those pools as a result. Once I left the dracut prompt and the pool was mounted on root, I noticed that the root pool was not using /dev/disk/by-partuuid.

Afterwards the zpool.cache file can be copied from the bootfs to tmp (or elsewhere), allowing a 'zpool import -c /tmp/zpool.cache' to import the pools as they were last used by the system.

Could you take a look at #2087? I'm trying to rewrite all this into a set of scripts that will work for everyone, everywhere.

I'm not sure what would be the point in checking each

for dir in /dev/disk/by-*; do
    zpool import -ad $dir
done

(which would be a more, non-hardcoded way, because I don't have by-partuuid or by-partlabel). If a disk/partition isn't in by-id, then there's something wrong with udev and that should be fixed. Not force ZFS to go around bugs in other softwares.

I do like (and signs off on) your ^-$ commit though and have merged that into my pull request (or at least will very shortly).

Initramfs scripts for ZoL.

* Put in /usr/share/initramfs-tools/ or /etc/initramfs-tools/.
* With pull request openzfs#1476 (not yet merged) comes a verbose warning
  if /usr/bin/net doesn't exist or isn't executable. Just create
  a dummy...
* If user haven't specified pool, but bootfs then use the first part
  of the bootfs path as pool name.
* Add support for booting of a ZFS snapshot.
  Do this by cloning the snapshot into a dataset. If this the resulting
  dataset already exists, destroy it. Then set mountpoint=/ on that
  dataset and mount it on root.
  + If snapshot does not exist, use base dataset (the part before '@')
    as boot filesystem instead.
* Add support for more kernel command line arguments (ideas taken from
  the Fedora/Redhat dracut script):
  + (zfs_force|zfs.force|zfsforce)=(on|yes|1) (ignore case).
  + root=zfs:AUTO => try to find rootfs automatically.
  + root=zfs:<dataset>
  + root=ZFS=<dataset>
* Remove the existing '-f' option to 'zpool import', instead let
  this be controlled on the kernel command line.
* Do not force-set mountpoint=/ - should (??) not be nessesary.
* Support mounting a rootfs with mountpoint=legacy
* Support both RPM based and DEB based system by removing the logic
  from the dracut script and instead use the logic in scripts/zfs-initramfs/scripts/zfs
  for both Debian GNU/Linux (etc) and RedHat/Fedora (etc).
* Only run the local-* script(s) if/when it/they exists.
* Don't auto import pools when loading module - keep better control of the imports.
* If called with only 'rpool' (or only 'zfs-bootfs'), then fake it by setting 'root=zfs:AUTO'
  (to avoid duplication of code etc) so that it will be auto detected later.
  + If pool is specified and we're auto discovering, don't go through ALL pools, only the one we specified.
* Rewrite the auto detection of bootfs in the auto detector.
* Only try to import pool if it haven't already been imported (in the auto detector).
* Add support for only having 'root=pool/dataset' option.
* Remove the use of setting 'ZFS_RPOOL=rpool'. No longer nessesary.
* Check if /scripts/local-* is either file or directory - should be dir, but just to be safe check both.
* Make wait_for_udev wait for 10 seconds.
* Add a configurable ZFS_INITRD_POST_MODPROBE_SLEEP (set in /etc/default/zfs) after the modprobe.
* Merge openzfs#2196.

Initramfs scripts for ZoL.
7926667 
* Put in /usr/share/initramfs-tools/ or /etc/initramfs-tools/.
* With pull request openzfs#1476 (not yet merged) comes a verbose warning
  if /usr/bin/net doesn't exist or isn't executable. Just create
  a dummy...
* If user haven't specified pool, but bootfs then use the first part
  of the bootfs path as pool name.
* Add support for booting of a ZFS snapshot.
  Do this by cloning the snapshot into a dataset. If this the resulting
  dataset already exists, destroy it. Then set mountpoint=/ on that
  dataset and mount it on root.
  + If snapshot does not exist, use base dataset (the part before '@')
    as boot filesystem instead.
* Add support for more kernel command line arguments (ideas taken from
  the Fedora/Redhat dracut script):
  + (zfs_force|zfs.force|zfsforce)=(on|yes|1) (ignore case).
  + root=zfs:AUTO => try to find rootfs automatically.
  + root=zfs:<dataset>
  + root=ZFS=<dataset>
* Remove the existing '-f' option to 'zpool import', instead let
  this be controlled on the kernel command line.
* Do not force-set mountpoint=/ - should (??) not be nessesary.
* Support mounting a rootfs with mountpoint=legacy
* Support both RPM based and DEB based system by removing the logic
  from the dracut script and instead use the logic in scripts/zfs-initramfs/scripts/zfs
  for both Debian GNU/Linux (etc) and RedHat/Fedora (etc).
* Only run the local-* script(s) if/when it/they exists.
* Don't auto import pools when loading module - keep better control of the imports.
* If called with only 'rpool' (or only 'zfs-bootfs'), then fake it by setting 'root=zfs:AUTO'
  (to avoid duplication of code etc) so that it will be auto detected later.
  + If pool is specified and we're auto discovering, don't go through ALL pools, only the one we specified.

* Remove the use of setting 'ZFS_RPOOL=rpool'. No longer nessesary.
* Check if /scripts/local-* is either file or directory - should be dir, but just to be safe check both.
* Make wait_for_udev wait for 10 seconds.
* Add a configurable ZFS_INITRD_POST_MODPROBE_SLEEP (set in /etc/default/zfs) after the modprobe.
* Merge openzfs#2196.
  Remove lines that contain only a hyphen (match '^-$' instead of '-').
* Add a 'default' file to go in '/etc/default/zfs'.

Initramfs scripts for ZoL.
* Put in /usr/share/initramfs-tools/ or /etc/initramfs-tools/.

Correct autodetection of bootfs property
d54da1f 
Remove lines that contain only a hyphen (match '^-$' instead of '-').

I had a root fs with a hyphen in the name (fedora/ROOT/Fedora20-Dev),
it was not detected because sed eliminated that line of output from
'zpool list -Ho bootfs'.
