No, Sugar does not have an execution hook at that point, but with
careful programming it could be added.
We used to have one for the Welcome activity, but that wasn't taken by
Sugar Labs upstream. You might look through the patches in Sugar Labs
trac or OLPC trac for "welcome".

That's not a Sugar question, but is relevant to OLPC OS.
olpc-configure is part of the olpc-utils package, and uses
.olpc-configured to figure out if it should run again.
If you want a script you write to run once, then make a marker and
test for it, e.g.
[ -e .adam-configured ] && exit
# (add here the things you want done once)
See man [, search for -e
See man bash, search for &&

You haven't described the use case. Perhaps Sugar Labs would like to
make this easier in future, whatever it is you are doing.
You want to change a gconf setting, for which you've used gsettings
rather than changing schema.
gsettings tries to update the older dconf key storage area.
dconf isn't happy with your context; e.g. maybe you are in the wrong
seat or some environment variables are missing.
My guess is that the gconf setting has been changed anyway; can you
confirm by doing "gsettings get" on it?
Does the "gsettings set" work in a Terminal activity started from
within Sugar? I think it does.
Or it is a matter of decoding the source code for dconf to find
out why it is failing.
