\fBi386\fP / \fBamd64\fP / \fBarmel\fP
Only available on i386 and amd64 systems.
This is optional; default is the native architecture
If \fBi386\fP is specified, an i386 environment will be used.
If \fBarmel\fP is specified, an armel environment will be used.
Note that there is no support for amd64 chroots on i386 systems
\fBarchitecture\fP
This optional parameter will attempt to construct a chroot in a foreign
architecture. For some architecture pairs (e.g. i386 on an amd64 install),
the chroot will be created natively. For others (e.g. armel on an i386
install), qemu-static and binfmt-misc will be used. Note that some
combinations (e.g. amd64 on an i386 install) require special separate
kernel handling, and may break in unexpected ways.
