Well, 'svnadmin load' is far from the only time eatmydata is useful to
a sysadmin. Anything that is transaction-based and you're doing a lot
of at a time can benefit, from cleaning a spam infestation out of a
mail spool, to a package-manager-managed system upgrade in a disposable
So, in general, the advice is, "if you're doing something that involves
a lot of disk syncs, but in circumstances where you care a lot more
about speed than crash-safety, you should have a look at eatmydata." I
prefer this approach over adding a "fast but unsafe" mode to every tool
that might be used in such a situation.

Could we just use a similar environment variable in this case as well?
The known use case is svnadmin, which is self-contained - no need to
propagate the flag to a separate server process - so a variable would
