The thing to realise is that the 'seen' flag tells debconf that the user
has seen the question, and that it should therefore not be asked it
again. Also, that setting something via preseeding automatically sets
the seen flag (otherwise the user would get asked the question anyway,
so preseeding would be a bit useless)
So, you need to reset the 'seen' flag to 'false' _after_ setting the
value you want it to default to.
In the above, in the commented section you're setting it to false before
setting the value, so that only survives for a moment before being
automatically set again, and in the lower attempt you're setting 'seen'
to 'true' (which prevents the question being shown, and is redundant
anyway because it just got set true by the preseed setting just above).
I'd normally do it thus:
d-i netcfg/get_hostname unassigned-hostname
d-i netcfg/get_hostname seen false
d-i netcfg/get_domain unassigned-domain
d-i netcfg/get_domain seen false
HTH
