git diff --diff-filter=D --name-only HEAD@{'7 days ago'}

finds files deleted during the last 7 days, but if my repository is
only 6 days old I get a
fatal error.

fatal: bad object HEAD@{7 days ago}

Is there something that says "since repository creation", ie., go back as far
as possible, but no further? Is there a symbolic name for the initial commit?

There's no symbolic name for it, since there might not be only one initial
commit. git.git for example has at least three root commits. You will
probably get what you want with $(git rev-list HEAD|tail -1). If your
history is very large, $(git rev-list --reverse HEAD|head -1) is slightly
faster, but usually not enough to offset typing --reverse :).

Thanks for this, but I'm a little confused.

If I do a "git init", there must be a first commit after this? Isn't
this the first commit, how
can there be more than one first commit?

In git.git, the gitk subdirectory has a separate root because it was merged
with the subtree merge strategy, so if you go down the second parent of that
merge commit, you'll end up not at the start of the git history. You can
see this if you just fetch any other repo into your current one and merge it.
Just add everything with conflict markers in if it conflicts and commit,
then look at gitk :). (and obviously then revert the merge or whatever).

Btw, after you git init, there are 0 commits, the first commit is created
when you run git commit the first time.
