This is already possible. With current genkernel (genkernel-9999 or |
| 7 |
genkernel-3.4.10.903), you can boot with 'docache unionfs', which will copy the |
| 8 |
squashfs to tmpfs, mount it, and then use unionfs-fuse to create a union with |
| 9 |
another tmpfs. |

Genkernel has offered the 'docache' option for quite a while, which has mostly |
| 12 |
the safe effect, but without the unionfs, it uses nasty tricks like copying some |
| 13 |
stuff to a tmpfs and then doing lots of symlinks into the squashfs. |

Either way, it's entirely memory based after initial boot. |
