Possessive for "it" is "its" .. not "it's".

Dhcpcd does not set your hostname by default.  This is quite desirable,
since more and more people are using dhcp to connect via their cable
modems.  

Anyhow, type 'man dhcpcd-bin' for more in how to make it set your
hostname via dhcp.  That is, of course, if you are using dhcpcd.  You'll
probably have to edit the wrapper script at /sbin/dhcpcd if you really
desire this behaviour.  

Still, why not just set your hostname at /etc/hostname, and be done with
it?
