# From the .deb's Depends/Recommends plus the ELF's actual NEEDED set.
# Cowork runs its agent in a KVM microVM: the client execs
# qemu-system-x86_64 from PATH, probes virtiofsd at /usr/libexec/virtiofsd
# (where Gentoo installs it) and OVMF firmware at /usr/share/OVMF/ (Debian
# layout -- bridged by the compat symlinks installed below).
