>Description:
	Currently DTrace requires the kernel being uncompressed.  It
would be desirable to have it automatically use corresponding
decompress libraries to access kernel if it's compressed with e.g.
gzip(1).
>How-To-Repeat:
	gzip /boot/kernel/kernel (with loader support of LOADER_GZIP_SUPPORT,
which is default), boot the system and try dtrace -l.
>Fix:
	Not yet.  This is a note so it wouldn't be forgotten.
