Subject: make.sh: Use devtmpfs to initialize /dev
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2b0ecf4df598d89694442700e5da9acbd502c923;p=people%2Fms%2Fipfire-2.x.git

make.sh: Use devtmpfs to initialize /dev

If we set up our /dev manually, we fail to deal with dynmically allocated loop
devices which are more common on modern distributions.
