Possible move to Help Desk Supervisor

Hi guys and gals, Right now I'm a Level 2 tech. During my mid year review last week, my boss mentioned that a change might be coming at our Service Desk Supervisor and he thought of me moving into the role. Well the change happened very quickly like yesterday and I have a sit down with my boss to discuss the opening on Thursday.
My ultimate goal is IT management, my boss is VP of IT & Infrastructure Operations at a 7 billion dollar bank, he thinks is a good move and natural progression for where I want to go. I'm just scared that it could be a dead end , just like long term help desk level 1 jobs, albeit I will be a supervisor of 5 service desk techs and would help with Level 2 day to day operations.
I always thought I would get more technical experience to get a management job, just got CCENT and currently studying CCNA.
Your thought?

If this is truly your goal, then you need to accept the promotion. Just know your list of responsibilities is not going to get smaller and everyone from the CEO's office to janitorial will be on your jock for something they need done.
Protip - Prioritize your schedule above all else. If you take lunch at 1pm, take it every day like clockwork. Do not cater to those who do not value your schedule and put hard limits on what you are or are not willing to do, within reason of course. Otherwise, Jan in accounting is going to run you over.
Edited to add - If you do this long enough, your day will feel somewhat incomplete if you don't get compared to the spawn of Hitler (direct quote from a phone conversation a week ago) from some a-hole in marketing. I'm not sure thriving on conflict is a good thing or not.
