[Tails-ux] Tor relay on Tails

I asked this question on the Tor relay mailing list, but I thought I should also ask this mailing list as well.
Is running a Tor relay through Tails a good idea? I'm thinking it isn't because Tails isn't meant for long term uptime, and I'm guessing running a relay through the Tor network itself just wouldn't be compatible, but perhaps one of you more educated Tor/Tails users could tell me better.
