and to write the logfile inside the kernel compile dir.
- turn the whole reorder_kernel function into a subshell {} -> ()
- create kernel compile dir early on
- redirect all stdout/stderr to a logfile inside this dir
- setup ERR trap handler that
- disables the EXIT trap handler
- syslogs the error and hints to the logfile
- additionally sends this message to the console
- setup EXIT trap handler that syslogs success
- wipe only the content instead of the whole kernel compile dir
- reestablish stdout redirection to the log after the wipe
- remove -q option of sha256 to log check result
- run reorder_kernel() in the background

- check for and exit if /usr/share is on a nfs mounted filesystem
- add trap handlers that mail the logfile to the admin user
- use $_compile instead of $_compile_dir like in the installer
- use $_compile/$_kernel instead of $_kernel_dir
- remove the now redundant sha256 -h ... after make newinstall
- write stdout/stderr of the background subshell to a logfile

presume we booted from.  If you boot from another kernel, we cannot help
you later with hibernate, sorry -- The kernel does not get a useable
filename from the bootblocks.
In the bootblocks, detect a live hibernate signature and boot from
/bsd.booted instead.
