| 25 | <para>Powerpc64 is slightly different from some of the other
|

| 26 | architectures, because a 64-bit kernel running 32-bit userspace can
|
|---|
| 27 | successfully chroot and execute 64-bit programs. However, if the
|
|---|
| 28 | kernel personality has been set to 32-bit by a utility such as
|
|---|
| 29 | linux32, it will eventually fail when Glibc thinks it is building
|

| 30 | on a 32-bit system and tries to include incompatible assembler code

| 31 | in the 64-bit glibc.</para>
