Depending on what you want to do, you might not have to install both a |
| 29 |
64 & 32 bit version of the kernel, when you compile the kernel for amd64 |
| 30 |
processors it has the kernel option CONFIG_IA32_EMULATION, which will |
| 31 |
allow you to run 32 bit applications while running the 64 bit kernel. |
| 32 |
If you want even closer to a full 32 bit environment, you can setup a 32 |
| 33 |
bit chroot. The only thing you would really need to do a complete |
| 34 |
second install (kernel & everything) is if you actually want to test a |
| 35 |
32 bit version of the kernel itself. |
