I believe that the "mount_md" is the one in /etc/rc.subr as I don't see any other mount_md. I started md-device a lot in these days. Given that, I have suggestions: 1. Make mount_md in /etc/rc.subr obsolete. 2. Rename "mdmfs" to "mount_md". 3. Make another option that enables "newfs" 4. Make "mount_md" NOT to "newfs" and "mount_mfs" to DO "newfs" by default. 5. Don't forget about my patch. :p 5.1 http://docs.freebsd.org/cgi/getmsg.cgi?fetch=564035+0+archive/2006/freebsd-current/20060416.freebsd-current The reasones for the above suggestions are: 1. Because we will create another one. 2. Because we can put it in fstab and "mount" can call it. "mdmfs" is simply a wrapper to "mdconifg," "newfs," and "mount" so that I don't see it attractive. I'd say too many options to think about and pass to a single program. On ther other hand, if it is called "mount_md", it is diffrent. 2. I don't think "mount_mdfs" is appropreate because it is not a filesystem. 3. Because I want to do #4. 4. "mount_mfs" historically did "newfs" and as a matter of fact, it is not functional unless done. However, none of mount_* calls do "newfs." Therefore, "mount_md" better not to do "newfs" when invoked. 5. This patch helps to mount uzip or partitions in md-devices. Regards, Hiro
