You can already do this in rc.conf:
---snip---
location=at_home
case ${location} in
at_home)
ifconfig_xx0="..."
...
;;
at_work)
ifconfig_xx0="..."
...
;;
*)
echo wrong location set
exit 1
# alternatively use some kind of default setup
;;
esac
---snip---
This way you need to know before where you are, or boot into
single-user mode. You can also extend it to read a kenv
("location=$(/bin/kenv profile.location)"), this way you can specify
the location in the loader (bonus points to implement a loader
extension in forth to read a file which lists possible profiles and
offer them in the menu).
Bye,
Alexander.
