Agreed, but I was only responding to the comment that building on an SSD |
13 |
was no slower than tmpfs. |

I can't agree with the second part, a tmpfs has far less space than a |
19 |
disk. I had a gcc build fail this morning when /tmp filled up. Not |
20 |
because gcc needs more than I had but because another emerge had failed |
21 |
and left a G or two in /tmp. You'll always have more disk space than |
22 |
RAM - embedded aside. |
