Define "safe". Command is filesystem agnostic and expects fully
preallocated file; it writes on block level. It also builds full content
of environment file in memory before writing it out; so it may fail on
systems with small amount of memory.
It attempts to verify that file can be represented by block lists and it
does not overwrite blocks outside of allocated for the file.
