[systemd-devel] [PATCH] importd: add CAP_DAC_OVERRIDE capability

[Lubomir Rintel]

Fedora's filesystem package ships /usr/bin (and other directories) which are
not writable by its owner. machinectl pull-dkr (and possibly others) are not

  14182 mkdirat(3, "usr/bin", 0500)       = 0
  14182 openat(3, "usr/bin/[", O_WRONLY|O_CREAT|O_EXCL|O_NOCTTY|O_NONBLOCK|O_CLOEXEC, 0700) = -1 EACCES (Permission denied)
