Axios (Still in a journey to find a decent backup os)
2 cents: Endeavour is solid. The Arch way is the arch way. It's sound. I think it's high maintenance but I don't mind it.. You may have a handful of updates in a day. It's not uncommon to get 2 kernel upgrades in one day I kid you not. Then reboots. You have to update your own reflectors, mirrors, and do a monthly cleaning. I like the terminal so all that stuff is second nature now.
In comparison Solus has about 2-3 eopkg commands I use to clean and I empty journalctl every month. Easily doubled in Endeavour but I like it.
It's solid as a #2.
I think you would love Alpine and it's MUSL world it's a tinker server for sure. Stuff that was stable that bored me: Debian, Fedora, Ubuntu, Mint, Suse...tried them all 2-3 times to be fair. Lots of strengths but you fall head over heels or you don't. That's probably half of it anyway.
Solus has always done it.
PS---the hunt for a solid #2 took me about a year and a half. I hope yours goes faster 🙂
MODS SORRY I DIGRESS!
