The run interface read like a library's. `ecrou run -it alpine` now
hands the guest a terminal: with no console output file, libkrun wires
the guest console to the process's own stdio and raw-modes the tty.
The parent saves and restores the termios around the run, because
libkrun's own restore lives in the child's exit observers, which a
SIGKILLed machine never runs. A tty run refuses to start without a
terminal on stdin and stdout, and --capture refuses to combine with
-t: the payload's streams cannot land in files and on the terminal at
once.
-i without -t keeps the machine's stdin open through pipes: libkrun
exposes the non-tty streams as virtio console ports (krun-stdin,
krun-stdout, krun-stderr), and the guest init points the payload's
stdio at whichever port nodes exist. `echo hi | ecrou run -i alpine --
cat` crosses the machine; a stream the host left on a tty has no port
node and stays on the console.
-v (--volume HOST:GUEST[:ro]) replaces --share, and -w aliases
--workdir. The global -v/--verbose loses its short flag to make room;
verbose stays reachable by its long form.
A reference starting with ./, ../ or / names a local rootfs archive:
read in place on every run, never downloaded, never cached as a
pristine entry. Provisioning over one persists into a derived cache
entry keyed by size and mtime, so the caller's file is never
overwritten and an edited archive lands in a fresh entry.
core26 base, strict confinement, the kvm interface for acceleration
with home and network auto-connected. The runtime needs nothing else:
the host process never mounts a filesystem and never creates or
enters a namespace, so it already lives inside snapd's default-deny
seccomp allowlist. The built .snap artifact is ignored.
