BINFMT.D(5)binfmt.dBINFMT.D(5)NAMEbinfmt.d - Configure additional binary formats for executables at boot
SYNOPSIS
/etc/binfmt.d/*.conf
/run/binfmt.d/*.conf
/usr/lib/binfmt.d/*.conf
DESCRIPTION
At boot, systemd-binfmt.service(8) reads configuration files from the
above directories to register in the kernel additional binary formats
for executables.
CONFIGURATION FORMAT
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.
Each configuration file shall be named in the style of program.conf.
Files in /etc/ override files with the same name in /usr/lib/ and
/run/. 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 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 /dev/null in
/etc/binfmt.d/ bearing the same filename.
