Hi,
We are seeing the following problem with the df in coreutils version 8.23
(which we call /usr/bin/gdf on Solaris to differentiate it from the "native"
version):
Now I realize that the latest version of the GNU df utility doesn't list
all mounted file systems by default, it skips that it calls "dummy" file
system.
However I noticed that on S12 the "/" file-system is no longer showing up
with "gdf -h". It works fine on Solaris 11.2 which has coreutils 8.16).
Here's what I see on my machine running Solaris 12 build #70:
$ gdf -h

Compare this with the Solaris "native" df:
$ df -h

You'll notice that gdf no longer shows the "/" file-system:
rpool/ROOT/os-s12-b70-take2
457G 13G 310G 4% /
Paul (Eggert) mentioned that adding the -a option gives the correct output:
$ gdf -h -a

but it suggests that there might be a bug here, and "/" should be
there without the need to specify -a.

From a cursory look at the output, I'm not sure there's going to be
enough information to go on there, so if you can suggest places where
I should add debug to .../coreutils-8.23/src/df.c (or wherever), then
I'll do that, and send on that output.
Thanks.
