I'm trying to mount a USB stick with an MS-DOS file system on it, and I'm specifying -o sync. This mount works in RELENG_6, and the source for mount_msdosfs.c makes me think it should work in -CURRENT. However, this is what I see: # mount_msdosfs -o sync /dev/da1s1 /mnt mount_msdosfs: /dev/da1s1: Invalid argument And in dmesg: mount option <sync> is unknown Mount point /mnt had 1 dangling refs So the kernel is rejecting this option. I looked through the kernel code, and it doesn't look like this option is in fact supported by msdosfs. However, I can't see why it works in -STABLE. Give that mount_msdosfs.c looks like it wants to support MNT_STDOPTS as well as MNT_SYNC, I'd think that sync should work. I haven't tracked down exactly why this is happening yet, but I'd appreciate any pointers. I'm running: FreeBSD fugu.marcuscom.com 7.0-CURRENT FreeBSD 7.0-CURRENT #72: Sun May 7 00:51:14 EDT 2006 gnome_at_fugu.marcuscom.com:/space2/obj/usr/src/sys/FUGU i386 But others have reported the same thing on more recent -CURRENT as well.
