Anyone here who has used Entware on Metarouter (ROS 6.x on MIPS)?

Hi, it looks like there are not that many discussions about running Entware on Metarouter (I’ve found only single one). So, before throwing time into learning how to get it done, I’m wondering if there may be major pitfals/obstacles with using Entware on Metarouter that I will hit with 99% probability (so there is no reason to even start)))
So, does anybody know (preferable from experience), if Entware integrates well with MT via Metarouter (stability, ease of use, compatibility for basic features)?

My reasoning for using Entware (as suggested on another forum) is to get Zerotier and full Mosquitto MQTT on my mAP2nd that is MIPS (thus no “new” containerisation available in ROS 7).

I was trying to solve it via OpenWRT in Metarouter, but with high probability I will fail, as newer OpenWRT versions that do support Zerotier may fail to fit into mAP2nd’s memory (still figuring out re compilation etc).
