Mount /fd, /proc, /srv and /shr in initcode
and open /dev/cons instead of #c/cons.
This way, /boot/boot could theoretically be a rc-script
and there is less reliance on magic device characters.

- avoid print() format routines (saves alot of code)
- avoid useless opens of /dev/cons (already done by initcode)
- avoid useless binds of /env and /dev (already done by initcode)
- do bind of /shr in bootrc, it is not needed by us
- we'r pid 1 so kernel will print the exit message for us

we want devip to get reattached after hostowner has been written. factotum
already handles this with a private authdial() routine that mounts devip
when it is not present. so we detach devmnt before starting factotum,
and attach once factotum finishes.
|
|
devip remembers the attach uname so after we set hostowner we
remount devip so future connections have the right owner.
|

we did not interpret the $rootdir and $rootspec environment
variables right. $rootdir is what gets bound to / (usually /root)
and $rootspec is the mountspec of /root.

mechanism to pass arguments to /boot/boot

theres a bootstrap problem:
when /bin/init is run, it processes /lib/namespace where we might want to
mount or bind resources to /n or /mnt. but mntgen was run later in
cpurc/termrc so these mounts would be ignored.
we already have mntgen in bootfs, so we can provide these mountpoints early.
i keep the termrc/cpurc mntgens where they are, but ignore the error
prints. this way old kernels will continue to work.

bootmkfile will now looks for the following proto files in order
and pick the first one it finds to build the bootfs.paq file:
1) $CONF.boofs.proto (config specific)
2) bootfs.proto (kernel specific)
3) $BOOTDIR/bootfs.proto (default generic)

secstore addresses
factotum is started in bootrc before the network is setup
(as we need it to negotiate wpa key for wifi). once, the network
is setup, the bootstrap authservers are passed in /net/ndb,
which factotum reads when doing bootstrap authdial. it does
this only when no authserver was specified earlier! but we
want net.rc to select the proper bootstrap authserver...
the $secstore variable takes precedence over $auth. as
there is no connection server yet, we have to select the set
of servers here and pass them to secstore with -s flag.
note that this will work if multiple addresses where
specified.

to run aux/wpa at boot, we need factotum to be running. tho
factotum was started only after the network was configured.
what we do now is start factotum early, not fetching keys
from secstore. once network is available and the auth server
is known, we fetch keys from secstore using auth/secstore in
bootrc.
to pass the authserver for p9 authentication to factotum, we
write it in /net/ndb and the special _authdial() in factotum
will picks it up.
as we are using auth/secstore binary in any case, we remove
the duplicated secstore code from factotum and make it just
exec auth/secstore to fetch the keys on startup (unless -n
or -S is specified).

still configurable, but with usbwait. If usbwait is not defined then it defaults to the original 2 seconds.

assuming that this check tried to prevent the hostowner
from killing init, it is silly because init would just
handle the note.
with kbdfs, we actually want to send interrupt note to
the initial process group so instead of working arround
this with rfork(RFNOTEG|RFNAMEG), we remove the check.
|
|
these changes make the interrupt key available in the
console (before rio is started).
kbdfs: will now send a "interrupt" note to its invoking
process group in cooked mode.
bootrc: is now prepared to handle interrupts, mainly to
not accidently spawn a new bootargs prompt.
init: forwards the interrupt to the cpurc/termrc pgrp.
vncs: shields itself from kbdfs notegroup so interrrupt
wont kill the whole vnc session.
