qemu-ifup is a traditional qemu script. The one in this patch is
almost identical to the ones included in KVM releases.
Also, it's meant to be modified by the user -- the user may want to
replace the 'brctl show | awk' expression with the name of a bridge,
especially if the host has more than one. I think a python script
will be awkward to modify.
Also, traditionally this script resides in /etc, and this one is
provided only in case the user doesn't have a better one in /etc.
The script in /etc is normally a bash script.
I have no problem with rewriting this as a python script -- I just
think it's more natural to keep this one in bash.
In python it would look something like:
import sys, os, commands
switch = commands.getoutput("/usr/sbin/brctl show").split()[1].split()[0]
os.system("/sbin/ifconfig %s 0.0.0.0 up" % sys.argv[1])
os.system("/usr/sbin/brctl addif %s %s" % (switch, sys.argv[1]))
There's nothing 'pythonic' about this. It looks like it should be a
bash script. It also looks simpler in bash. Anyway, if you like this
better, or if you think the 'python only' policy should apply here,
no problem.
