Some other points I think we need to be consistent on:
- Spacing around string concatenation (always)
- Test against 'nil' explicitly rather than relying on 'not' for things that
reasonably won't be returning a boolean. e.g. loader.getenv
Eventually this will all get formalized somewhere.
Once we've successfully loaded a kernel, we add its directory to
module_path. If we switch kernels with the kernel selector, we again prepend
the kernel directory to the current module_path and end up with multiple
kernel paths, potentially with mismatched kernel/modules, added to
module_path.
Fix it by caching module_path at load() time and using the cached version
whenever we load a new kernel.
In a similar fashion to FILE, provide thin shims for the standard directory
manipulation functions.

These are the style points that I'd like to try and maintain in our lua
scripts:
- Parentheses around conditionals
- Trailing semicolons, except on block terminators
- s:method(...) instead of string.method(s, ...) where applicable
There's likely more, but that'll get hammered out as we continue.
Prompt for GELI passphrase when geom_eli_passphrase_prompt has been set to
"YES" in loader.conf(5).
This entailed breaking out the password prompt into its own function that
can be reused between the password compare bits and this prompt that simply
takes the entered password and passes it along in the environment as
kern.geom.eli.passphrase.
I've also added a TODO to re-evaluate later if we want the "password
masking" -- it is currently not functional, so one still can't observe the
length of the password typed at the prompt.
This is the procedure that config.loadkernel tries to go through, but
reloading kernel config didn't use this function. Amend config.loadkernel to
take an optional other_kernel.
While here, be a little more verbose ("Trying to load kernel") so that it's
easy to follow where we've gone wrong.
1.) Instead of string.function(s, ...), use s:function(...)
2.) Don't try to concatenate `res`, it was just tested to be nil
3.) Note that "Loading configuration" is configured modules, and be a little
more precise in mentioning what failed ("loading of one or more modules")
An empty module_path to start with isn't ideal, but if all modules are
contained within a kernel directory (which is what we just tested) then it
isn't strictly an error. Don't assume that module_path has a value already.
When we fail to load the kernel, printing the result (which is guaranteed to
be nil) is not intended; print the name of the kernel.
autoboot_delay=NO is documented to wait for input and *not* autoboot, which
is the exact opposite of the current behavior.
Additionally, autoboot_delay=-1 is documented to disallow the user from
interrupting the boot (i.e. autoboot immediately), which was not previously
honored.
This also fixes the case insensitive comparison to be truly case
insensitive. This is kind of nit-picky, but the previous version would only
accept "no" and "NO".
Don't move this into config.reload because we may want to force reloads if
/boot changes out from under us later.
As a caution: changing kernels in lualoader at the moment might not be
loading all of your modules (in my testing, at least) from loader.conf(5).
This is a known problem.
Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."
This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.

ffs_sbget() may return a superblock buffer even if it fails, so the
caller must be prepared to free it in this case. Moreover, when tasting
alternate superblock locations in a loop, ffs_sbget()'s readfunc
callback must free the previously allocated buffer.

This is a pre-cursor to boot environment support in lualoader. Create a new
menu item type, "carousel_entry", that generally provides a callback to get
the list of items, a carousel_id for storing the current value, and the
standard name/func functions that an entry has.
The difference between this and a normal menu item, functionally, is that
selecting a carousel item will automatically rotate through available items
and wrap back at the beginning when the list is exhausted.
The 'name' function takes the choice index, current choice, and the list of
choices as parameters so that the menu item can decorate the name freely as
desired.
The 'func' function takes the current choice as a parameter, so it can act
accordingly.
The kernel menu item has been rewritten to use the carousel_entry type as
both an example and initial test of its functionality before it is used for
boot environment options.
Noting that we're in lualoader is nice, but it's not a difference we raelly
need to expose to Fred. Re-word it to match the 4th wording and reduce
differences.
This removes a redundant alias that has since been converted into a global
alias. It was converted to a global alias before to ensure that we always
have a way to go up one level in the menu.
Set it based on hint.acpi.0.rsdp. Initially, hint.acpi.0.disabled will be
respected. "Using System Defaults" will override whether it's explicitly
disabled by hint and re-load it based on whether it's present on the system.
Unlike the 4th version, this is not restricted to x86. I have no strong
reasoning for this, so this is definitely open to change.
This submenu is likely going to go away in favor of kernel selection as it
is done in forth at the moment, but for the time being don't descend into it
if we have no kernels available for listing.
OK. We don't really need a bsd.stand.mk, and it was causing a -fPIC
for the toolchain to be added (bogusly) when building on amd64. Pull
all relevant defs back into defs.mk and delete bsd.stand.mk.
This saves about 15-20k on i386 loader and zfsloader which when
combined with Lua give us a lot more stack space in those constrained
environments.
bootp/arp/rarp/rpc all use the sendrecv implementation in net.c. tftp has
its own implementation because it passes an extra parameter into the recv
callback for the received payload type to be held.
These sendrecv implementations are otherwise equivalent, so consolidate
them. The other users of sendrecv won't be using the extra argument to recv,
but this gives us only one place to worry about respecting timeouts and one
consistent timeout behavior.
