Hi, I need to test my server which started to have problems recently. I placed the disk elsewhere to spin up and the remaining crappy hardware I wanted to test thoroughly from LiveCD. I wanted to emerge some packages into the live system but it failed: # emerge cpuburn dbench piozone bashmark [cut] >>> Source compiled. >>> Test phase [not enabled]: app-benchmarks/cpuburn-1.4 >>> Install cpuburn-1.4 into /var/tmp/portage/app-benchmarks/cpuburn-1.4/image/ category app-benchmarks >>> Completed installing cpuburn-1.4 into /var/tmp/portage/app-benchmarks/cpuburn-1.4/image/ Traceback (most recent call last): File "/usr/bin/emerge", line 6971, in ?

The LiveCD doesn't currently use unionfs (there's forthcoming support) and the root filesystem is squahsfs, which is read-only by nature.
