beware of JamMo!
The installation packages are enormous. They clogged up my system, then failed in mid-installation, leaving my poor little Ubuntu unusable. It took me a week until I realised there’s no avoiding root shell access (well, to be honest – I was walking in the Peak District most of it). Today I dived in, removed the jammo packages, removed its repository from the sources list, and rebooted. Haaaa. Nice to see that familiar screen again.
Now all I need to figure out is why my windows has gone blue-screen-of-death.
