Scenario:
=========

- Using virtualbox-5.1.12 to run FreeBSD head amd64 (currently at r308341).
- Installed, amongst other, the following ports:
  . arm-none-eabi-binutils-2.27_5,1
  . arm-none-eabi-gcc-6.3.0
  . qemu-user-static-2.7.90.g20161116_1
- Via iSCSI importing a disk (disk925) with an arm/armv6 installation, mounting its partitions as follows:
    /dev/diskid/DISK-HAL_00925s2a /d/925s2a         ufs     rw              0 0
    /dev/diskid/DISK-HAL_00925s1 /d/925s2a/boot/msdos       msdosfs rw             0 0
    devfs                   /d/925s2a/dev           devfs   rw              0 0
    fdescfs                 /d/925s2a/dev/fd        fdescfs rw              0 0
    procfs                  /d/925s2a/proc          procfs  rw              0 0
    /dev/md1                /d/925s2a/tmp           ufs     rw              0 0
- Via autofs mounting FreeBSD ports:
    hal:/z/SRC/FreeBSD-ports /d/925s2a/auto/z/SRC/FreeBSD-ports nfs rw             0 0
- Chrooting into the arm environment and starting a zsh there:
    # chroot /d/925s2a /bin/zsh -l
- This now runs the emulated zsh.
- Compiling a new version of ports-mgmt/pkg:
    # cd /usr/ports/ports-mgmt/pkg
    # make
- Up to here, everything works.

Results:
========

- Since a few weeks, the following happens:
- Portmaster does not find any ports to upgrade (the following message "all ports are up to date" is wrong):

[0]# portmaster -gaB
===>>> Starting check of installed ports for available updates

===>>> All ports are up to date

[0]# 

- Manually installing a new version of 'pkg' results in (first install via tar, then in the normal manner):

[0]# cd /usr/ports/ports-mgmt/pkg
[0]# ( cd /usr/tmp/ports/ports-mgmt/pkg/work/stage/usr/local && tar cf - . ) | ( cd /usr/local && tar xfp - )
[0]# make install clean

Expected results:
=================

- A few weeks ago, apart from the unimplemented cap_* system calls, everything worked fine.
