That information could be obtained by conclusion and
by experience. I had the experience that it might
interfere with a regular fsck (not the background one)
if present. Only at a background run you'd have the
opportunity to remove .snap, whereas during a normal
fsck run (typically at startup) you cannot do this
(without interrupting fsck).
Anyway, you're right: fsck_ffs's source code mentiones
the .snap directory. It's line 320 and later. The comment
at line 283 suggests that fsck will _create_ that
directory if required, just like dump -L would do.
Line numbers for /usr/src/sbin/fsck_ffs/main.c OS
version 8.2-STABLE here, may differ for others.
So there may be an extension of my summary:
It is permissible _unless_ you are running the dump
program on a live partition using the -L option -or-
you are currently running (background) fsck.
