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.
