Usage: $0 [extract] [-o DIR|--output=DIR]
Update the system trust store in $DEST.
COMMANDS
(absent/empty command): Same as the extract command without arguments.
extract: Instruct update-ca-trust to scan the source configuration in
/usr/share/pki/ca-trust-source and /etc/pki/ca-trust/source and produce
updated versions of the consolidated configuration files stored below
the $DEST directory hierarchy.
EXTRACT OPTIONS
-o DIR, --output=DIR: Write the extracted trust store into the given
directory instead of updating $DEST.
