Supplement:
After a reboot, the flawed output of mount(8) (and df(1)) disappeared.

Hello folks,
I just spotted a very strange bug on 11.1-RELEASE.
(It might be fixed already?)
While working with my ZFS (mirrored pool / 2 SSDs), I wanted to
originally track 11-STABLE and moved my original /usr/src around.
The original steps were:
1) zfs snapshot lazarus/usr/src@RELENG_11.1
2) zfs clone lazarus/usr/src@RELENG_11.1 lazarus/usr/src-RELENG_11.1
3) zfs promote lazarus/usr/src-RELENG_11.1
4) zfs destroy lazarus/usr/src
...
So nothing too fancy (lazarus is the name of my pool).
I didnt first notice, but after doing this I get now intermixed output
while using mount(8) and df(1).
EXCERPT
-----------------------------------------------------------------------
lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/ada3p3 on
/virtuals/therion/images (ufs, local, journaled soft-updates)
lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/zvol/lazarus/home/therion.eli on
/home/therion (ufs, local, journaled soft-updates)
lazarus/usr/src-RELENG_11.1@RELENG_11.1/dev/fuse on /home/therion/.gvfs
(fusefs, local, nosuid, synchronous, mounted by therion)
-----------------------------------------------------------------------
So what is happening here is that the
"lazarus/usr/src-RELENG_11.1@RELENG_11.1" is prepended to the original
lines, which would normally *not* include this.
This doesnt happen with all lines.... only these ones - after the last
line it continues with:
192.168.0.5:/warehouse on /warehouse (nfs, nosuid, nfsv4acls, mounted by
therion)
lazarus/usr/src on /usr/src (zfs, local, nfsv4acls)
so just normally...
The RELENG_11.1 dataset I've created is not mounted:
EXCERPT
-----------------------------------------------------------------------
root@lazarus:~ # zfs get mounted lazarus/usr/src-RELENG_11.1
NAME PROPERTY VALUE SOURCE
lazarus/usr/src-RELENG_11.1 mounted no -
-----------------------------------------------------------------------
Has anyone ever spotted this?
I suspect a parsing error while consuming the information mount(8)
needs, wherever this information comes from.
regards,
Georg
