I agree with you, that SliTaz is be the best choice for all those baytrail, cherrytrail, braswell Atoms - especially if you need windows on it for some special programs as I do - but the problem is, that I think, that 4.11 will not work well together with very old libc of SliTaz 5.0 - I would not bet, but I think it could be some kind of wasted time.
Hopefully we get soon a testing basic 6.0 iso from Aleksej - so it would be good, if you can test it, as soon as it is available.
Can you test in the meantime galliumos for me - especially, if everything works and if there is different battery time - like on my dell the battery time with galliumos is about 30% better than in win10. Galliumos uses slightly different patches than linuxium - this would be good to know!
