So far, everything parsed root= manually, which meant that while zfs-parse.sh was updated, and supposedly supported + -> ' ' conversion, it meant nothing Instead, centralise parsing, and allow: root= root=zfs root=zfs: root=zfs:AUTO root=ZFS=data/set root=zfs:data/set root=zfs:ZFS=data/set (as a side-effect; allowed but undocumented) rootfstype=zfs AND root=data/set <=> root=data/set rootfstype=zfs AND root= <=> root=zfs:AUTO So rootfstype=zfs /also/ behaves as expected, and + decoding works Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #13291
