Nope, unless mkfile is is guaranteed to give you contiguous space:
# uname -a
SunOS vmsol8 5.8 Generic_108529-05 i86pc i386 i86pc
# mkfile 100m a.a
# swap -a /a.a
# swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0d0s1 102,1 8 1048936 1048896
/a.a - 8 204792 204792
Pages are pages. The filesystem handles the
details for the offset of
each one. There's no contiguous on disk requirement.
I've used at least one *ix OS that required it be both contiguous and
pre-allocated; Slowaris?
