Misc 1 : Qemu launching
1) A script to make qemu launching automatic
Sometimes, the list of commands one has to type as host can be very long and tedious; and forgetting to type one of them leads to unpleasant results (ex : a mounted image should be unmounted before being used by qemu)
a bash script like this one, once adapted, might give ideas to avoid errors..
echo " image pour qemu : ${NOM_IMAGE:=armadeus-qemu.img}
montee dans ${NOM_DIR_MNT:=qemu-mnt} "
echo -e " repertoire de transit : ${TFTBOOT:=tftboot}
rafraichissement ${rafraichir:=no}
options -rw ou ro- : ${OPTION:=rw}
RAM :${RAMSIZE:=96M} DISQUE: ${DISKSIZE:=160}
image de boot :${VMBOOT:=./vmlinuz-2.6.29.6-versatile-armadeus}

Nota : this script has been tested and run with some satisfaction for one month on Scientific Linux - 5.7 (a Red Hat clone, able to mount NTFS partitions and having a live DVD) and a Mageia-1: emulated cards were apf9328 and apf27.
Nota : Some things are very unstandard : using /usr/local as a working directory on ones host is a consequence of lazy mounts on a Scientific Linux live DVDD.... The size of the disks and the RAM do not need to be realistic, as it is meant for some tests (and lacking 500 K of disk , without tools to test it, might be frustrating)
Nota : copies which are made on an emulated image wo not appear on real hardware....
