Partition sizes for DNS server?

[Albert Meyer]

I'm building a DNS server, and since it was my first Linux server I kind of
hacked it together and got it working (and learned some stuff about Linux in
the process) and now I'm going to start over and try to do it right. I have
a 2G HD, and I'm thinking of setting up the partitions like this:

/	~5G
/etc	~5G
/var	~10G
/swap	128M

Is that right, or would another config be better? I'm running RH 6.2 and
Bind 8.2.2, and have 128M RAM. There won't be any users or anything running
on the box besides DNS.
