Sure, it's totally reasonable.

First off, the suggestion was made in a comment, it's just an offhand bit of advice, and I'm confident the person who made the suggestion is aware that it's not always trivial to switch to a different OS.

But if you're having trouble with the exact sequence of processes and services starting, and if another distribution has better tools to control the sequencing, that's a useful and legitimate answer for anyone else who comes across the question.

It might not be useful to you because of factors that aren't mentioned in your question, but that's what upvotes and accepting are for.  If another answer comes along and explains how to do what you want in the distribution you're using, then you'd upvote and accept that answer.  Even if "use a different OS" was the only answer you got, you could still leave a comment and say that's not an option.

And the fact that they're mods isn't relevant, but the fact that they're #3 and #15 in total reputation is an indication that they have a lot of knowledge and experience, so maybe it is worth considering the suggestion.
