I like ZFS, but I decided that my puny little 25W 1.3 ghz CPU was gonna
choke on checksums & not get anything else done, hence the switch back
to UFS. I came up w/ a slightly hairbrained solution. I created a stripe
of the 3 remaining 20 GB partitions, copied everything under /usr over
to it, & plan to mount it as /usr. 1 question: as of now, /usr is taking
up 1.1 GB out of 1.7 GB on my 20 GB root partition. With such a limited
root FS, I want every available byte available for duty. Is there any
way to delete what's under /usr on the fly before the mount of the /usr
stripe to recover that space back for the rest of the install ? I have
only done the base install as of now, will be installing X, XFCE, LXDE,
& who knows what else ....
P.S. sorry for me klutzy nomenclature, I am calling /dev/ada0p3 a
partition, when as you correctly observe it is a device .... my bad, &
maybe the source of confusion in my posts :-/ ....
