21 | <para>Powerpc64 is slightly different from some of the other |

22 | architectures, because a 64-bit kernel running 32-bit userspace can |
---|
23 | successfully chroot and execute 64-bit programs. However, if the |
---|
24 | kernel personality has been set to 32-bit by a utility such as |
---|
25 | linux32, it will eventually fail when glibc thinks it is building |
---|
26 | on a 32-bit system and tries to include incompatible assembler code |
---|
27 | in the 64-bit glibc.</para> |
