# We see sometimes corrupted uboot.env files created by fsck.vfat.
# On the fat filesystem they are indistinguishable because one
# has a fat16 name UBOOT.ENV (and not lfn (long-file-name)) but
# the other has a "uboot.env" lfn name and a FSCK0000.000 FAT16
# name. The only known workaround is to remove all dupes and put
# one file back in place.

    # not matter which one we pick (we can't choose anyway, we get
    # whatever the kernel gives us). The key part is that there is
    # only a single one after this script finishes. The bootloader
    # logic will recover in any case.
