UML の環境 その 2

udev入れたのに MACアドレス指定していなかった。で eth# が無いとエラー。 /etc/udev/rules.d/z25_persistent-net.rules を消すという姑息な手段で逃げる。ちょっと長くなるけど uml_switch の起動スクリプト。debian のものをちょこっと変更しただけ。

exit 0

更に同じディレクトリに linux というバイナリがある前提の起動用

if [ -z $1 ]; then
   echo "what number?" 1>&2
   exit
fi

nohup ./linux \
    ubda=rootfs_$1 \
    ubdb=swap_$1 \
    mem=64m \

いや、こんなこと や dhcp の冗長とかやってみたくて...
