is called before the compile process so a build that requires the user to exist will |

have it, and is also called for both binary and source packages. You may also |

use the <c>pkg_preinst</c> or <c>pkg_postinst</c> functions for user creation, if |

<c>pkg_preinst</c> is the preferred location for a few reasons. If |

The user/group is added on the build host even if it is not |
| 22 |
required to build the package. |

The user/group is created when simply unpacking the sources of a |
| 27 |
package with <c>ebuild foo.ebuild unpack</c>. |

<li> |

The user/group remain on the system if compilation or installation |

fails. |

<p> |

However, there is a situation where the user/group <b>must</b> be |
| 38 |
created in <c>pkg_setup</c>: when it is needed during compilation or |
| 39 |
installation; that is, in <c>src_compile</c> or <c>src_install</c>. |

| 43 |
If the build process requires the user/group to exist, then it |
| 44 |
should be created in <c>pkg_setup</c> instead of |
| 45 |
<c>pkg_preinst</c>. Likewise, if <c>chown <user></c> or other |
| 46 |
similar commands are executed during the installation, then the user |
| 47 |
must already exist at that point, and so should be created in |
| 48 |
<c>pkg_setup</c>. |
