Is something missing here?

FreeBSD% sudo dtrace -l
   ID   PROVIDER            MODULE                          FUNCTION NAME
    1     dtrace                                                     BEGIN
    2     dtrace                                                     END
    3     dtrace                                                     ERROR

dwatch -X open doesn't work either:

FreeBSD% sudo dwatch -X open
INFO Sourcing open profile [found in /usr/libexec/dwatch]
INFO Watching 'syscall::open:entry, syscall::openat:entry' ...
dtrace: failed to compile script /dev/stdin: line 1: probe description syscall::open:entry does not match any probes

Solution: Use sudo kldload dtraceall instead of sudo kldload dtrace.

Looking at which files the Linuxulator accesses still doesn't work like this:

FreeBSD% sudo dtrace -n 'linux64:*open*:entry { printf("%s %s", execname, copyinstr(arg0)); }' 
dtrace: description 'linux64:*open*:entry ' matched 5 probes
(...)
dtrace: error on enabled probe ID 1 (ID 76713: fbt:linux64:linux_openat:entry): invalid address (0xfffffe00f72adc00) in action #2 at DIF offset 12
dtrace: error on enabled probe ID 5 (ID 76477: fbt:linux64:linux_common_open:entry): invalid address (0xfffffe00f72adc00) in action #2 at DIF offset 12
dtrace: error on enabled probe ID 1 (ID 76713: fbt:linux64:linux_openat:entry): invalid address (0xfffffe00f2e7d500) in action #2 at DIF offset 12
dtrace: error on enabled probe ID 5 (ID 76477: fbt:linux64:linux_common_open:entry): invalid address (0xfffffe00f2e7d500) in action #2 at DIF offset 12

Why?
