I just ran an rpi-update and now the rootfs filesystem is 100% full. During the boot process I am seeing the following messages:
gzip: /var/log/dmesg.0.gz - No space left on device
Starting system message bus: dBusFailed to start message bus: Failed to close "/var/run/dbus/pid": No space left on device
I have a 4GB SD card.
df -k shows the rootfs is 1602524 in size
uname - a
Linux raspberrypi 3.1.9+ PREEMPT Wed Jul 25 22:11:06 BST 2012 armv61 GNU/Linux
Any help on releasing some space gratefully received
