<groan> ... another boot option...

Can we just set this to something sane, and then make a sysctl or
something else at runtime to tweak it?  The kernel won't use IMA much
before userspace comes up, and it can surely live with a slightly
suboptimal tuning until the boot scripts have a chance to go bang the
tunable.

We should reserve command-line parameters for things that really need
tweaking in early boot or are _needed_ to boot.
