--- Comment #2 from Eugene Grosbein <eugen@freebsd.org> ---
(In reply to Kirk McKusick from comment #1)

Yes, this is mounted and live file system and files are created here.

Does UFS2+SU snapshot guarantee that dump won't get uninitialized indirecti=
on
blocks from the file system if snapshot creation occurs at same moment?

I still believe dump should not loop forever and should perform some sanity
checks on indirection blocks.
