|

| 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>
