180 --help: display this usage
181 --qemu-path: set path to qemu interpreter ($QEMU_PATH)
182 --qemu-suffix: add a suffix to the default interpreter name
183 --debian: don't write into /proc,
184 instead generate update-binfmts templates
185 --systemd: don't write into /proc,
186 instead generate file for systemd-binfmt.service
187 for the given CPU. If CPU is "ALL", generate a
188 file for all known cpus
189 --exportdir: define where to write configuration files
190 (default: $SYSTEMDDIR or $DEBIANDIR)
191 --credential: if yes, credential and security tokens are
192 calculated according to the binary to interpret
193 --persistent: if yes, the interpreter is loaded when binfmt is
194 configured and remains in memory. All future uses
195 are cloned from the open file.
197 To import templates with update-binfmts, use :
199 sudo update-binfmts --importdir ${EXPORTDIR:-$DEBIANDIR} --import qemu-CPU
201 To remove interpreter, use :
203 sudo update-binfmts --package qemu-CPU --remove qemu-CPU $QEMU_PATH
205 With systemd, binfmt files are loaded by systemd-binfmt.service
207 The environment variable HOST_ARCH allows to override 'uname' to generate
208 configuration files for a different architecture than the current one.
