Being able to run 32-bit binaries requires two things. x86_32 support in |
| 13 |
the kernel (which (no-)multilib doesn't affect) and all the libraries for |
| 14 |
the binaries being available in a 32-bit version, particularly ld.so and |
| 15 |
libc.so.6; multilib the multilib profile causes (not "allows" -- if you |
| 16 |
use multilib profile it is not optional) the most fundamental 32-bit |
| 17 |
libraries (like those required for *building* a 32-bit library) to be |
| 18 |
installed. |

That's true as far as libraries go. (A fully statically linked 32-bit |
| 24 |
executable could still run if the kernel has support for x86_32.) |

Saves disk space and compilation time. |

Very few F(L)OSS programs are unavailable in 64-bit land, so if your |
| 35 |
computer lives in the "Free (Software) world" you won't have problems no |
| 36 |
matter what you use the computer for. |

|
| 38 |
If you need/want proprietary binaries, multilib is the only way to go. |

Not I. I'm still leaning on my wine/cedega crutch for some things. |
