Sorry for keeping you waiting.

Maybe lets use cap_helpers in whole file

What you afraid of?
If you build system without capsicum/casper everything works caph_enter_casper don't fail in that case, the filearsgs_open is changed to the standard open(2) call>
Please check ot this header file: https://svnweb.freebsd.org/base/head/lib/libcasper/services/cap_fileargs/cap_fileargs.h?view=markup

Simplify #2.

Simplify.

@allanjude Would you be interested to try sandbox uudecode with fileargs?

Can we abandom this review?

I think we can close this revision because of the: https://reviews.freebsd.org/D17967

The idea looks good for me, but I'm not an expert about Makefiles so I would feel bather if @bdrewery would give a look to those changes.

I would wait one day for @pjd

I didn't check that, but I wonder what would happen if we would past the AT_FDCWD? Which have a negative value.

@cem, @kib, @emaste, @jilles I would like to commit it as-it-is but pjd suggested to change the name to funlinkat? After some thoughts I also think that funlinkat is a bether name 'fd' suggests that it's working on 'FILE *'. Do you agree?

What is a point of it?
If you have a legacy mount do you want to mount it?
What about importing the pools that are missing?

@mjg ping

Thanks for catching that.

Few more comments.

LGTM.

Wow Amezing job! Thank you for working on that!

Why don't use casper for that (e.g. cap_sysctlbyname) ?

LGTM.

One minor change. Besides that LGTM.

I proposed some minor changes.

@emaste The part about Casper LGTM.

LGTM
