The engine's dlopen of libkrunfw and mke2fs's of libarchive use bare
sonames, and dyld reads DYLD_FALLBACK_LIBRARY_PATH once, at process
startup — a setenv afterwards is invisible to it. When the variable
is unset and the brew kegs exist, the CLI sets it and execv's itself:
exec restarts dyld, which reads the variable fresh. Library consumers
set the variable before their process starts instead (SPEC.md).
ecrou's workspace starts from ecr's confinement-neutral half: image
reference resolution, the content cache with digest freshness, layer
extraction with whiteouts and deferred directory modes, provisioned
hot cells, and the progress/error/config plumbing. Adaptations: the
cache lives in ~/.cache/ecrou, the namespace-era error variants and
utils constants are gone, KvmUnavailable arrives ahead of its caller,
rootfs loses its exec() delegation, and uname(2) goes through libc
now that nix is no longer a dependency. The CLI crate is a stub until
its commit.
