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’t 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=200191 Bugzilla Bug 200191: blkid does not rewrite blkid.tab as documented in the man page. ...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 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
