Did this already with my former RPI and I'm not using an extra USB Disk. Building the toolchain takes ~300, kernel ~50 and world ~800 minutes. I'm using a 1 GB swap partition and tmpfs (not md) for /tmp and /var/tmp, no problem so far. root@pizelot:~ # swapinfo Device 1K-blocks Used Avail Capacity /dev/mmcsd0s2b 1048576 9548 1039028 1% root@pizelot:~ # df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/mmcsd0s2a 1015324 63940 870160 7% / devfs 1 1 0 100% /dev /dev/mmcsd0s2d 8106716 3897656 3560524 52% /usr /dev/mmcsd0s2e 8106716 163200 7294980 2% /var /dev/mmcsd0s2f 8106716 16 7458164 0% /home tmpfs 1224992 40 1224952 0% /tmp tmpfs 1224956 4 1224952 0% /var/tmp -asc
