binfmt.d — Configure additional binary formats at boot
/usr/lib/binfmt.d/*.conf
/etc/binfmt.d/*.conf
/run/binfmt.d/*.conf
systemd uses files from the above directories to configure additional binary formats to register during boot in the kernel.
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 is named in the style of
<program>.conf
.
Files in /etc/
overwrite
files with the same name in /usr/lib/
.
Files in /run
overwrite files with
the same name in /etc/
and
/usr/lib/
. Packages should install their
configuration files in /usr/lib/
, files
in /etc/
are reserved for the local
administration, which possibly decides to overwrite the
configurations installed from packages. All files are sorted
by filename in alphabetical order, regardless in which of the
directories they reside, to ensure that a specific
configuration file takes precedence over another file with
an alphabetically later name.
