Would it be possible now or in the future to use an SD Card on a laptop as a
cache for ZFS?
I've been trying to do this with OpenSolaris 1108 on a Dell XPS M1530 laptop.
The SD Card is presented as /dev/rds

zpool add syntax again. If you need help with the
format syntax, let me know.
This command syntax should have complained:
