Description

Right now ztest executes zdb without -G, so when it has errors, the messages are often not very helpful:

Executing zdb -bccsv -d -U /rpool/tmp/zpool.cache ztest
zdb: can't open 'ztest': Operation not supported
ztest: '/usr/sbin/amd64/zdb -bccsv -d -U /rpool/tmp/zpool.cache ztest' exit code 1

With -G, we'd have:

/usr/sbin/amd64/zdb -bccsv -d -U /rpool/tmp/zpool.cache -G ztest
zdb: can't open 'ztest': Operation not supported

ZFS_DBGMSG(zdb):
spa_open_common: opening ztest
spa_load(ztest): LOADING
spa_load(ztest): FAILED: unable to parse config [error=48]
spa_load(ztest): UNLOADING

Which indicates where the error came from
