nmount(2) also fails without [ENOENT,ENOTSUP].
An example is when there is a tmpfs mounted with -o size. vfs_filteropt() adds
'size' as an error in errmsg due to 'size' not being in tmpfs_updateopts. Then
tmpfs_mount returns [ENOTSUP] from nmount(2), which is then ignored. The next

The race itself is a separate issue to fix as it is expected to have an

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

to populate the $PKG_ABI global (called in a way that allows implicit
bootstrap of pkg(8)). The solution to which was to find every place in
bsdconfig(8) that requires the $PKG_ABI global and add a layer of
protection by way of introducing the new API call f_musthavepkg_init()
(provided by new include, `/usr/share/bsdconfig/packages/musthavepkg.subr'
intented to mirror `/usr/share/bsdconfig/mustberoot.subr'). When the
$PKG_ABI global is required, you can use `f_musthavepkg_init' to cause
graceful premature termination in the event that pkg(8) has not yet been
bootstrapped, and thus cannot be used to populate $PKG_ABI.
NB: If running interactively ($nonInteractive is NULL or unset), the
f_musthavepkg_init() API call will attempt to bootstrap pkg(8), but only
if the user chooses "Yes" to a Yes/No dialog confirming it is ok to
bootstrap.
