Bug#387370: 'notail' default mount option for reiserfs partitions.

[Teodor <mteodor@gmail.com>]

The default mount option for the / reiserfs partition is 'notail'. Is
this something of concern?

According to the http://en.wikipedia.org/wiki/Reiserfs article, this
option is RECOMMENDED:

  "Tail packing, a scheme to reduce internal fragmentation. Tail
packing, however, can have
    a significant performance impact. Namesys recommends disabling the
feature in
    performance-critical applications"

Please note that for any other reiserfs partition besides /, the mount
option is just "defaults",
which in practice gets interpreted as "rw".

Thanks
