99 .SH OVERVIEW
1010 The 2.6.27 kernel brings the ability to support external metadata arrays.
164164 containers with names longer than 5 characters, this argument can be
165165 arbitrarily extended, e.g. to
166166 .BR \-\-all-active-arrays .
167 .TP
168 .BR \-\-offroot
169 Set first character of argv[0] to @ to indicate mdmon was launched
170 from initrd/initramfs and should not be shutdown by systemd as part of
171 the regular shutdown process. This option is normally only used by
172 the system's initscripts. Please see here for more details on how
173 systemd handled argv[0]:
