>Description:
Some programs (e.g. an older version of the LiViD DVD
software) appear to rely on the write(2) behaviour of OSS --
namely, that it writes only whole `fragments' and that the
`fragment' size initialize to a power of 2 >=1024. That is,
they write 1k blocks and do not check for short writes.
Such programs currently malfunction under our OSS emulation.
>How-To-Repeat:
Obvious from above.
>Fix:
Not supplied, and may be annoying. Should check existing
Linux documentation (if any) to determine if the program's
expected behaviour is actually correct.
