Description
Mounting a non-root FAT file system over TMPFS root and doing:
/tmp # cp /readme /data/a /tmp # ls /data/a /tmp # cat /data/a
will result in the corrupted contents of /data/a. The reported file size will be correct, but the last few tens of bytes will look like duplicated from the beginning of the file.

This is actually a problem of the bdsh implementation of cp. If the write() needs to be done multiple times during the copy, it is essential to move the buffer address according to the bytes written. Already fixed in lp:~jakub/helenos/fs.

Not reproducible if the root FS is FAT too.
