[SPARCbook] homebase script

[Patrick Arnoux]

# The following script may come in handy for people running 2.6
# who regularly switch between different networks.
# 
# The script just copies the current set of files from "/etc" to the
# directory named after the current domain name (to save modifications),
# copies the files from the requested domain name directory into "/etc"
# and changes the IP address and default gateway.
# 
# The hosts file must contain an entry by the name "router"
# to setup the default gateway
# 
# To run it the first time, just create an empty directory for the
# current domain and the modified hosts/resolv.conf/defaultdomain
# files in the target domain directory.
# 
# Pretty simple stuff, and probably more verbiage than the code is worth.
# 
# 
# In any case, I hope someone else can find it useful. Enjoy!!
# 
# Oh, and if you live an a .net or .org domain, you know what to do :)
