192        --help:          display this usage
193        --qemu-path:     set path to qemu interpreter ($QEMU_PATH)
194        --qemu-suffix:   add a suffix to the default interpreter name
195        --debian:        don't write into /proc,
196                         instead generate update-binfmts templates
197        --systemd:       don't write into /proc,
198                         instead generate file for systemd-binfmt.service
201        --exportdir:     define where to write configuration files
203        --credential:    if yes, credential and security tokens are
205        --persistent:    if yes, the interpreter is loaded when binfmt is
208        --ignore-family: if yes, it is assumed that the host CPU (e.g. riscv64)
211        --preserve-argv0 preserve argv[0]
213     To import templates with update-binfmts, use :
215         sudo update-binfmts --importdir ${EXPORTDIR:-$DEBIANDIR} --import qemu-CPU
219         sudo update-binfmts --package qemu-CPU --remove qemu-CPU $QEMU_PATH
221     With systemd, binfmt files are loaded by systemd-binfmt.service
