masys
A magit-style TUI for Linux system runtime ops, and one of
meowr's guest applications. systemctl-tui manages
units well; btop and htop monitor resources well; nothing does
both, and nothing applies magit's actual organizing idea — a status
buffer that shows what needs attention, rather than a dashboard that
shows everything.
A healthy machine produces a nearly empty screen. An unhealthy one puts
the problems under it, worst first — a failed unit, a pressure spike, a
disk running low — each buffer answering one question: what's running
and why (Procs), what the units are doing (systemd, over
zbus), what the disks and filesystems
are carrying (IO), and — on a host with a declarative platform adapter
like NixOS — what the running system and its declared configuration
disagree about (Nix). That last buffer doesn't exist at all on a
machine with no declared configuration to compare against; there's
nothing there for a digit to open.
