And we will have the same - several copies of the same code in each archi=
tecture,
which i have deleted...
Sparc doesn't support DIOCGMEDIASIZE and DIOCGSECTORSIZE ioctls,
so it will not check each partition, only fd that is passed to the zfs_pr=
obe_dev.
Currently there is only one problem with ZFS tasting, that can affect use=
rs -
now we taste each disk and partition, but in the my branch ZFS tastes onl=
y disks and
partitions with type "freebsd" and "freebsd-zfs". So if you have created =
ZFS on top
of MBR partition with type "ntfs", then loader will be unable to detect i=
t.
