Q: How to configure CONFIG_DEFAULT_RELATIME to disable relatime

user5528Since linux 2.6.30 filesystems are mounted with "relatime" by default. In this discussion, Ingo molnar says he has added the CONFIG_DEFAULT_RELATIME kernel option, which, i quote: "makes "norelatime" the default for all mounts without an extra kernel boot option." I don't really get it, i wonder...

Q: How to find human-readable information about file types recognized by `file`?

@Caleb Is that how we go about changing it? It seems odd for a geek site that zeros are rendered like that...
 
@jasonwryan The first thing to do is find some more example questions where that fonts glyphs are awkward in the context of Unix questions. Then open a question on the meta site that explains the issue. SE staff monitors that pretty closely and if we get some momentum behind it (particularly if we can suggest a better alternative) I'm sure they will change it.
 
@Caleb Cool: once I have gathered a couple three examples, I'll open a thread. Cheers.
