Last time I checked, Reiserfs was using 32 MiB for its journal, not 8.
Anyway, the capacity is not cut by several gigabytes, and you _do_
need a journal and an allocation table for _any_ fs.

Hard disks _are_ 100 GB when sold as 100 GB, just not 100 GiB (that
would be 107 MB), and I have the weakness to think that's good: G =
10^9, not 2^30.

Now stop moaning and enjoy your Ubuntu ;-)
