sharemgr show -P should probably recurse
Talking with Gordon about sharemgr he asked why -P didn't work.
It turns out that it does in fact work, but illogically. It does not recurse through groups, thus.
- sharemgr show -vp -> All shares
- sharemgr show -vpP nfs -> the default group
- sharemgr show -ppP nfs zfs/some/group -> The shares of zfs/some/group, assuming it is an NFS group
It's not clear to me whether this was the intended behaviour, but, as best as I can determine, it's useless behaviour.
Utility would stem from, at the least, recursing (such that the behaviour of -vp and -vpP were logically consistent).
