FYI: ext4 filesystem journaling (and swap) *should* be disabled

To reduce wear?
Yes.
I really don't think data-loss is an acceptable compromise just to
reduce wear.
Lack of a journal doesn't necessarily mean data loss. It just means
that you might need to run fsck.ext4 on the drive after unmounting.
Occasionally you do lose data: I think it has to do with crash
shutdowns twice in a row without an intervening fsck.ext4.

There are actually a couple of ways around the SD wear issue, even though
people seem to dearly LOVE SSDs with the exact same issue;
1.) Use a USB drive.
2.) Somewhat more esoteric, PXE boot and run from an NFS image.
The how-tos for the later seem to avoid talking about how to set up a proper
PXE boot environment using ISC DHCP, but I'll crack that nut shortly.
I love PXE and use it to install windows 7, freebsd, VMWare and a whole bunch
of Linux distros in my home lab
