For power-saving functionality or because of the `quality' factor? What is the criteria that determines the `quality' of a clock as what's being reported above (I know what determines the quality of a clock visually from a oscilloscope =])? I suspect that the quality of the HPET driver is lower simply because no one had measured it previously and HPET is newer and less "proven". From memory, HPET was massively slower on some of the AMD test hardware I was using. There was a thread about it on one of the mailing lists, but I can't find it right now.

Although longer to type, "less /README" would be a better alternative
than using vi to view the contents of the file. You could otherwise
risk the user destroying the README file due to unfamiliarity with
this particular editor.
OTOH, why not adopt OpenBSD's afterboot(8) man page?

Almost completely off-topic:
An /altroot mechanism would be nice to have in FreeBSD. ;-)
There are at least two schools of thought regarding /altroot.
One school of thought would be to simply dd the contents of the root
partition on to the altroot partition and run fsck on /altroot,
assuming /root and /altroot have the same size. I believe this is how
OpenBSD handles /altroot when configured to do so.
My school of thought, given a system with more than one hard drive,
physical or virtual (as in RAID volumes), is to have /altroot appear
as a regular root file system (partition a) on the other drive and
thus being able to (manually) boot from the available root file
system. Both hard drives should be made bootable with the EasyBoot
loader placed in the MBRs and with regular boot blocks in the FreeBSD
slices. Of course, /altroot should normally remain unmounted.
There is also the possible need of having /etc/fstab files with
specific contents for each root file system. For instance, /'s
/altroot should be mounted as /altroot's /. I'm not sure how to handle
this scenario with either installers as you probably need to perform
the installation twice, that's how I did it on a couple of recently
installed systems, not to mention how to handle make
install{kernel,world} for both of the two root file systems.
Just some random thoughts,
Trond.
