    SubjectVFAT: Can't create file named 'aux.h'?
    From
    Date

    Hi everybody,

    while trying to back up a couple Linux directories to a FAT disk I ran
    into a weird situation: I can't create a file called aux.h on the FAT
    system!

    Here's how to reproduce it:

    cd /tmp
    dd if=/dev/zero of=vfat_img bs=1M count=1
    /sbin/losetup /dev/loop7 vfat_img
    /sbin/mkfs.vfat /dev/loop7
    mkdir vfat_mnt
    mount -t vfat /dev/loop7 vfat_mnt
    touch vfat_mnt/auy.h
    touch vfat_mnt/aux.h

    auy.h is happily created, aux.h gives "touch: setting times of
    `vfat_mnt/aux.h': No such file or directory", and no file is created.
    This happened to me on the system described below, but I could reproduce
    the same behavior on a system booted from RHEL4 CDs, an old Knoppix
    (3.4), and friends could reproduce it on other systems, too, so it
    doesn't seem to be very related to a specific version.

    As a workaround I tar/bzipped my dirs, but that behavior seems very
    unusual and doesn't inspire a lot of confidence in vfat... What am I
    missing here?

    Thanks

    Dirk
