You can uncompress the stage files and such, but chroot will fail because |
| 42 |
you will be attempting to run a 64 bits bash binary against the 32 bits |
| 43 |
underlying kernel, which will not work. The opposite would be possible |
| 44 |
though, you can chroot to a 32 bit userland from a 64 bits kernel. But not |
| 45 |
the other way around. |
