I have sometimes wished that the native "netbsd" emulation tried
prepending "/emul/netbsd" to path names.  This would be useful for
sharing filesystems between NetBSD and another OS.  For example, last
time I tried booting a NetBSD/i386 kernel on a system that was installed
with FreeBSD, almost everything worked (with the NetBSD kernel running
the FreeBSD userland under emulation), but I wished that I could install
NetBSD versions of a few things under /emul/netbsd where they would not
get in the way when I booted a FreeBSD kernel again.
