alt Hacker NewsThe present is built mostly on layers of the long-past :)
It makes me think of when Arch merged /usr/bin and sbin with /bin and sbin. Having them split made sense in a ton of scenarios that used to be very common, but increasingly the split was vestigial for most users.
Yea, my understanding is that the split between / and /usr used to be more or less: the drive they used for / ran out of space, so they mounted another drive as /usr. As a consequence, / became where you put stuff that was essential during early boot, while /usr was where you put everything else.
But these days, "early boot" is handled by initramfs and we've all got drives large enough to not need the split anyway.
