Bug#719734: pcp: FTBFS: chown: invalid user: 'pcp:pcp'

["Aaron M. Ucko" <ucko@xxxxxxxxxx>]

Source: pcp
Version: 3.8.2
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of pcp in environments (as on the autobuilders) with no
existing pcp user or group have been failing:

  ./install-sh -o root -g root -m 775 -o pcp -g pcp -d /var/lib/pcp/config/pmda
  chown: invalid user: 'pcp:pcp'
  make[1]: *** [install_pcp] Error 1
  make[1]: Leaving directory `/ÂPKGBUILDDIRÂ'
  make: *** [binary-arch] Error 2

Given that pcp already allocates both dynamically, I would recommend
sticking with that approach rather than trying to move to static IDs,
and simply ensuring that pcp.postinst.tail adjusts all ownership and
permission settings appropriately (ideally via dpkg-statoverride, per
Policy 10.9.1).

Could you please look into it?

Thanks!
