NAME¶
binfmt.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.
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 of which of the directories
they reside in. 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.
EXAMPLE¶
Example 1. /etc/binfmt.d/wine.conf example:
# Start WINE on Windows executables
