Here also are the output of 'mount' and 'df -m'. I captured those because they seemed to contradict syslog's claims about the filesystems (/ and /home) having been mounted. But perhaps they were mounted then the installer umounted them before bouncing me back into the partitioner. At any rate:
rootfs on / type rootfs (rw)
none on /run type tmpfs (rw,nosuid,relatime,size=789216k,mode=755)
none on /proc type proc (rw,relatime)
