What's so impressive about Homebrew specifically?
1) Rarely breaks. Worst I've seen is needing a permissions tweak after an OS upgrade, in many years of use. Back when I switched from Macports I switched because ordinary usage kept rendering Macports so goddamn broken that it was easier to nuke its directory and start over rather than figure out how to fix whatever my bold command of "install package" had destroyed this time. I've never seen normal or even slightly…
I had it break before with weird cyclical linking issues, but mostly it works good enough.
What I was more curious about is what specifically sets it apart from a solid Linux package manager?
> Lets you manage your packages with ordinary user-level permissions. No root elevation required.
This is the one major difference I'd say is not currently common on Linux. Could be easily solved by keeping package list databases in $HOME - the only reason root is required nowdays is because these are usually kept as 1 copy per system.
