wait_for_loginit ends the log; this is unhelpful if you're using
emergency_shell to do debugging.
Just leave loginit running. It doesn't hurt anything.
copytree() recursively copies the contents of SRC into DEST.
If DEST doesn't exist it is created; if it exists the contents of SRC
get merged into it (duplicate files are overwritten).
If you unset CMDLINE to make _getcmdline re-read /etc/cmdline and
/etc/cmdline.d/*, CMDLINE_ETC and CMDLINE_ETC_D would keep their
contents.
This is a serious problem if you have (e.g.) "ip=eth0:dhcp" in
/etc/cmdline.d/net.conf, because getargs ip= will return
"ip=eth0:dhcp ip=eth0:dhcp" and then parse-ip-opts.sh will die() because
you have two configurations for eth0.
Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup

According to its comment in dracut-lib.sh:
splitsep ":" "one:all:the:rest" one two
should set two="all:the:rest". But there's no check to see if the
current field is the last field, so it just gets "all".
"export -n" is a bash extension, not part of POSIX, and is hence
incompatible with the busybox shell.
This was breaking boot when the busybox module was used.
Reimplement the scope change in a few lines of standard shell code.
wait_for_loginit does set +x (to turn off debugging temporarily), but
sometimes it would return before turning it back on. Move the set +x
line to fix that, then use 'setdebug' to make sure we don't turn it back
on unless it was needed.
The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).
The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
Manually setuping nic through udev is not always done when
we want network access. Here add a function wait_for_route_ok to
wait and make sure the network is accesible

Harald: don't use bash syntax
Add check for [ -n "$li" ] because `ip route show` will show nothing probably

if you add realinitpath="<path1> <path2>" to dracut.conf, then it will
be written to $initdir/etc/cmdline.d/distroinit.conf with
"rd.distroinit=<path1> rd.distroinit=<path2>" and evaluated by
99base/init, when it searches for init.
