the blkid manpage says:

	-w	<writecachefile>  Write  the  device  cache  to
		writecachefile instead of writing it to the default
		cache file /etc/blkid.tab. If you don=92t want to save
		the cache to the default file,  specify  /dev/null.
		If  not specified it will be the same file as that
		given by the -c option.

and yet, since:

http://thunk.org/hg/e2fsprogs/?rev/ad62cded89a8 (I think...)

(2003...) it has been completely ignored.

I have a bug on this, from before my time at Red Hat,
https://bugzilla.redhat.com/show_bug.cgi?id=3D200191  Bugzilla Bug 2001=
91:
blkid does not rewrite blkid.tab as documented in the man page.
=2E..filed in 2006.

It'd be easy enough to fix, although this might be a library API change=
,
at least if we want to make blkid_get_cache() symmetric with
blkid_put_cache(), each taking a filename...

But it's been broken so long, with (few) complaints, is the
functionality worth resurrecting, or should I just submit a patch to
remove the -w option?  :)

Thanks,

-Eric
