New in pkg-1.4-0 pkg: unlinkat(usr/local/): Read-only file system [Was: pkg-1.4-0 signal-4-exit with core-avx-i; FreeBSD:10:i386 vs. FreeBSD:10:32?]

After adjusting my scripts  to handle the new ABI, I now see the another
pkg(8) surprise:
'pkg delete -f pkg'
[1/1] Deinstalling pkg-1.4.0...
[1/1] Deleting files for pkg-1.4.0: 100%
pkg: unlinkat(usr/local/): Read-only file system
pkg: unlinkat(usr/): Read-only file system
pkg: unlinkat(usr/local/): Read-only file system
pkg: unlinkat(usr/): Read-only file system
… (repeted)


It's true that "/" is read-only, but "/usr/local" is rw of course.
pkg(8) mustn't touch anything on "/" for most packages, which is true
for "pkg" itself.
Can somebody explain the cause of these error messages with pkg-1.4.0?

Thanks,

-Harry
