BINFMT.D(5) binfmt.d BINFMT.D(5)
binfmt.d - Configure additional binary formats for executables at
boot
/etc/binfmt.d/*.conf
/run/binfmt.d/*.conf
/usr/lib/binfmt.d/*.conf
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[1] 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.
Configuration files are read from directories in /etc/, /run/, and
/usr/lib/, in order of precedence. Each configuration file in these
configuration directories shall be named in the style of
filename.conf. Files in /etc/ override files with the same name in
/run/ and /usr/lib/. Files in /run/ override files with the same name
in /usr/lib/.
Packages should install their configuration files in /usr/lib/. Files
in /etc/ are reserved for the local administrator, who may use this
logic to override the configuration files installed by vendor
packages. All configuration files are sorted by their filename in
lexicographic order, regardless of which of the directories they
reside in. If multiple files specify the same option, the entry in
the file with the lexicographically latest name will take precedence.
It is recommended to prefix all filenames with a two-digit number and
a dash, to simplify the ordering of the files.
If the administrator wants to disable a configuration file supplied
by the vendor, the recommended way is to place a symlink to /dev/null
in the configuration directory in /etc/, with the same filename as
the vendor configuration file. If the vendor configuration file is
included in the initrd image, the image has to be regenerated.
Example 1. /etc/binfmt.d/wine.conf example:
# Start WINE on Windows executables
:DOSWin:M::MZ::/usr/bin/wine:
systemd(1), systemd-binfmt.service(8), systemd-delta(1), wine(8)
