After a 'make world' and a new kernel from sources cvsupped ~10PM EST
last night, it seems that msdosfs is broken... Files that are known
to be good appear corrupt when accessed from FBSD.
This seems to characterize the problem:
# ls -l /dos/c/MISC/STAC.DOC
-rwxr-xr-x 1 root wheel 72417 Jan 30 16:22 /dos/c/MISC/STAC.DOC
# file /dos/c/MISC/STAC.DOC
/dos/c/MISC/STAC.DOC: Rich Text Format data, version 1, ANSI
# cat /dos/c/MISC/STAC.DOC
cat: /dos/c/MISC/STAC.DOC: Argument list too long
Compiled 'cat' with '-g', then:
>cat> gdb ./cat
