To be honest, I hate the idea of rewriting the network config; being
able to specify things like

config_eth0=( "10.1.1.{1..10}/24 brd +" )

(yes, it really expands correctly and works!) is extremely useful and
something you don't find in any other distro out there last time I've
checked. You can assign tons of IP address on a single line, or just
with a couple of lines if you need different subnets, instead of going
thru the boring and error-prone task of specifying every single address
separately.

Why kill such useful features just to get rid of arrays and bash?
