I really like pattern matching in Rust, but I find myself using it less and less. `if let` and `let ... else` require substantially less indentation, and I often use them for Option values. I don't miss this syntactic sugar in OCaml though. Maybe it's just because OCaml has a 2 space indent, unlike Rust's 4 space indent?

A cute systemd feature to get the system clock roughly correct: if the system time is before the compilation time of the systemd binary, it moves the clock forward to that time! https://lwn.net/Articles/714355/

Do users of immutable systems (i.e Nix or Guix) upgrade more or less often than other platforms? There's less pressure to upgrade (unlike a rolling release distro) but in principle upgrading is easier.
