binfmt.d — Configure additional binary formats for executables at boot
At boot, systemd-binfmt.service(8) reads configuration files from the above directories to register in the kernel additional binary formats for executables.
Each file contains a list of binfmt_misc kernel binary format rules. Consult binfmt_misc.txt for more information on registration of additional binary formats and how to write rules.
Empty lines and lines beginning with ; and # are ignored. Note that this means you may not use ; and # as delimiter in binary format rules.
Each configuration file shall be named in the
/etc/ override files
with the same name in
/run/. Files in
/run/ override files with the
same name in

/usr/lib/, files in
/etc/ are reserved for the local
administrator, who may use this logic to override the
configuration files installed from vendor
packages. All files are sorted by their filename in
lexicographic order, regardless in which of the
directories they reside. If multiple files specify
the same binary type name, the entry in the file with
the lexicographically latest name will be applied.
If the administrator wants to disable a
configuration file supplied by the vendor, the
recommended way is to place a symlink to
/etc/binfmt.d/ bearing the
