Hi,
ramdisk* hasn't been in place for quite a while now (I think since
the 5.x days when the mdconfig scripts were created). Could someone
please review and potentially commit this manpage update to remove the

Thanks!

If you want review for rc.d related stuff freebsd-rc@ is your best bet.
Meanwhile, this patch is fine, thanks for taking the time to look at it.
AFAICS neither 8 nor 7 has this feature either, so feel free to MFC.

What are you porting FreeBSD to?
I'm porting it to the MPC8555CDS which has a e500 ppc core.

You don't. It's not necessary. MD_ROOT_SIZE only reserves

find the offset in the kernel image, and then write your

Hi,
Would anyone know if how to pre-load modules of type `md_image' is
documented anywhere?
I'm trying to create a 250Meg ramdisk , but have only managed one of 10
Meg so far .
So far what I can surmise is that it has to be done in loader.conf:
1) Setting [mfs_load=NO] to YES
2) Somehow

Given all of the above statements, why does BSD/OS (at least on 4.0 and 4.1)
want to set up tmp as a Ramdisk? I don't even think there is a way around it
during the install.
