[Firehol-support] running FireHOL under busybox's ash-shell

[Costa Tsaousis]

Hi,

FireHOL needs array variables. The parentheses define such array variables
in BASH. The problem is that ASH does not support them (at least to the
best of my knowledge - and its man page).

Without array variables, FireHOL should be re-written to use file based
arrays, which will not provide any of the performance advantages ASH
offers (against BASH).

PS: I am sorry for this...
