What does the Apache "proxy:unix:..." handler do, and where is it documented? I see it used here and there, like:
SetHandler "proxy:unix:..."
For example in this recent question, or in the SetHandler and mod_fcgi documentation.
I can guess that it might pipe to a Unix socket, but what about the syntax in the mod_fcgi example? Where's the documentation?
This is a Canonical Question about when to use packaged software and when to build and install it yourself.
When should I install software from packages provided by my OS distribution, instead of building and installing it myself from source? When is it better to build from source?
What command can tell me the last time that a filesystem was fsck'd? A date would be nice, but I'd settle for the mount count since the last fsck.
I've looked all around for this in fsck*, lsattr, and stat, and I don't see it.
