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
Just because you could do this in RELENG_6,
did -o sync actually ever work in msdosfs?
There were a lot of inconsistencies in the old parsing of mount options,
where UFS specific mount options would just happen to "work", i.e.
"not fail" for other filesystems.
Anyways, you can try this patch:
