This allows the FS to just live, uncompressed, in cache.
This is generally a bad idea, however:
- In a hypothetically super-tuned diskless image, the lack of double-cache can offset the lack of compression
- The image will have supreme read performance
- It will have the most deterministic memory behavior
By default, the squashfs file was being cached as well as the contents after extraction.
This is superfluous pressure on the cache of the OS.
However, it does help keep the image afloat through 'confignet', so
leave it on until onboot completes, then reclaim cache and disable further caching.
Rather than treat both as the same, since untethered has everything up front anyway, go ahead and extract the filesystem.
This makes the mount look more straightforward and makes it so deletion of files from
the image also frees ram.
Reduce obvious output about skipped devices.
Rule out any read-only device.
Amend minimum size to 2GB.
Among same priority devices, select the smallest target.
If debugssh is not requsted, the initramfs is not needed.
Do not unshare the mount namespace, leave the kernel relevant namespace 'normal'
Remove some initramfs content to free up some memory.

A variant of the M.2 RAID enablement kit does not manifest with nvme
driver. Address this by allowing 'nvm' subsystype. to allow blank driver.
Also, to be on the safe side, have self.driver always be a string,
so it can be 'falsey' but still work as a string.
The infiniband section must be defined for the OS
to use the IB link. If it is missing then networking
does not come up during firstboot.
Fix this by having an inifiniband section including explicitly
declaring use of datagram mode. This should suffice for all
install use cases, and may be changed after firstboot starts.
If syncfiles fails, keep it retrying.
Also, slow down sync checking to avoid hammering the system.
Further, randomized delay to spread highly synchronized requestors.
Block attempts to do multiple concurrent syncfile runs.
Fix various callbacks when using IPv6 based deployment.
Do not attempt to restore erroneously cloned zram partitions.
Convert LVM names to new LVM names consistent with source naming scheme.
Push new kernel command line into /boot/loader and /etc/kernel/cmdline.
Some versions start manifesting nvme devnames with 'c', which
are to be used to interact with multipath to have raw devices
backing a traditional nvme device.
If the ip command shows altnames, do not
let the altnames interfere with locking
on to linktype.
Further, use show dev instead of grep to be more specific.
When booting and infiniband comes up as the 'get started' nic,
make the entry use correct type so as to avoid
confusion later, particularly when confignet comes along to fixup
the configuration.
