Hi Doug!
I confirmed that your zfsboot code is good on my i386/amd64 note
PCs after r186243! Thanks for your works!
I have two requests:
1. To support zpool for lsdev like following.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
OK lsdev -v
cd devices:
disk devices:
disk0: BIOS drive C:
disk0s1a: ZFS 72GB (63 - 151048055)
disk0s1b: swap 5120MB (302096047 - 312581808)
disk0s1a: ZFS 72GB (151048055 - 302096047)
pxe devices:
zfs devices:
pool: tank
config:
NAME STATE
tank ONLINE
ad4s1a ONLINE
OK
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
2. To support case of "slice has only zpool and no bsd partition".
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# zpool create tank ad0s1
and
boot from ad0s1
