Git detached head

[SAC020]

Am on the dev branch and I am seeing some "git detached head" messages in the log. I don't know if it's an issue, so just asking this in a discussion thread - is it something normal / expected?

thanks

detached head can happen due to any number of reasons, but its never critical.
sdnext installer takes care of it and re-attaches it as needed. but even if it were never reattached, only impact is that such repo cannot be automatically updated.
