Kernels built with a bare CONFIG_NETFILTER and the (relatively) new
CONFIG_TRIM_UNUSED_KSYMS (like our initramfses) have a high probability
of the nf_(un)register_net_hook functions being elided by the unused,
exported symbol trim pass.

So, move to using the base, non-wrapper functions (which can accept
multiple hooks) instead, since those aren't going to be elided.

(Also bump the version, missed that in 4a801b22 .)

Calling emergency_restart directly from the softirq/bh ipod icmp handler
has a history of causing panics prior to the intended shutdown on both
aarch64 and powerpc64.  The panics didn't inhibit the intended reboot,
but on OPAL-booted ppc64le, were very noisy, because each "hyperthread"
cpu attempted a dealloc of the irq handler from within the handler, so
the console got a noisy stack trace for each thread.

So now if IPOD_QUEUE_RESTART is defined (and it is by default on aarch64
and powerpc64), we move the call to emergency_restart into a dedicated,
preallocated workqueue thread, whose sole purpose is to (eventually)
reboot the machine.  Wasteful, but we don't want to need to initialize
anything, or use a shared workqueue, if an IPOD is really necessary, at
IPOD time.

This replaces the hardcoded partition length-based detection of which
MBR "version" is on disk, when deciding whether or not to rewrite the
MBR/GPT.  Now we just check the cited MBR/GPT version file, and use that
length to compare the first partition length.

We also prefer partprobe if it's available, rather than fdisk, for
forcing a rescan of the disk partition tables.

(ppc64le OPAL-booted machines won't actually have a bootloader installed
in the first sector, so there is no magic to look for.)

hardwire to apache22).

David is going to add this to prepare so we do not create images with
stale repos on them.

Mainly, this means tag create messages now have tag URLs; and that
annotated tag create messages now include more tag metadata, as well as
the referenced commit.

jacksmod is now a dependency of Jacks. In order to prevent loading problems, Jacks itself no longer loads jacksmod. So it is up to the surrounding page to load it properly now.

execute services. So for tainted images use the older method.

have to wait, they are instantly mounted on boss, but do not show up in
mount output.

Don't know why we did not hit this before. Maybe the node_usage DB
got into an odd state recently where there were some extra records?
Who knows. I compared the .dat files produced from old and new and
all the historic records that this script produces are the same.
