Ext2fs and noatime

[Carsten Kunze <carsten.kunze%arcor.de@localhost>]

Hello,

mount_ext2fs(8) says that it doesn't support option "noatime":

# mount_ext2fs -o atime
mount_ext2fs: -o atime: option not supported

Unfortunately the manpage of mount_ext2fs(8) doesn't specify which mount options are available.

Looking at the code at http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/ufs/ext2fs/ext2fs_readwrite.c shows that options relatime and noatime seems to be processed.  So why does the mount tool not support these options?

BTW:  Why is directory src/sys not downloaded with the kernel code when doing

$ export CVSROOT="anoncvs%anoncvs.NetBSD.org@localhost:/cvsroot"
$ cd /usr
$ cvs checkout -A -P src

?
