answerr: Is this "fake-pkg" process even running on the NFS mount? The WRKD=
IR is /tmp, which is an mfs mount.
fake-pkg is run in WRKDIR, but it calls pkgng which will open
/var/db/pkg/local.sqlite aka nfs mount.
The Error 70 is EX_SOFTWARE returned by pkgng.
Can you try the following patch:
http://people.freebsd.org/~bapt/patch-libpkg__pkgdb.c
Just add that file to /usr/ports/ports-mgmt/pkg/files/
If that works for you, that means the posix advisory locks is somehow faili=
ng on
nfsv4 files.
Given it is already known to be failing on nfsv3 (because people often
misconfigure it) I'll probablmy make unix-dotfile the default locking system
when local.sqlite is stored on network filesystem.

Bapt
