.SH "NAME"
binfmt.d \- Configure additional binary formats at boot
.SH "SYNOPSIS"
.PP
/etc/binfmt\&.d/*\&.conf
.PP
/run/binfmt\&.d/*\&.conf
.PP
/usr/lib/binfmt\&.d/*\&.conf
.SH "DESCRIPTION"
.PP
\fBsystemd\fR
uses files from the above directories to configure additional binary formats to register during boot in the kernel\&.
.SH "CONFIGURATION FORMAT"
.PP
Each file contains a list of binfmt_misc kernel binary format rules\&. Consult
\m[blue]\fBbinfmt_misc\&.txt\fR\m[]\&\s-2\u[1]\d\s+2
for more information on registration of additional binary formats and how to write rules\&.
.PP
Empty lines and lines beginning with ; and # are ignored\&. Note that this means you may not use ; and # as delimiter in binary format rules\&.
.PP
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\&.
