+Mirroring tip
+----------------------------------------------------------------------
+
+Having a local Fedora mirror makes a massive difference to the time it
+takes to build and rebuild initramfs images.
+
+Failing that, use squid to cache yum downloads, but read this first:
+https://lists.dulug.duke.edu/pipermail/yum/2006-August/009041.html
+(In brief, because yum chooses random mirrors each time, squid doesn't
+work very well with default yum configuration.  To get around this,
+choose a Fedora mirror which is close to you, set this with
+'./configure --with-mirror=[...]', and then proxy the whole lot
+through squid by setting http_proxy environment variable).
