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 :-/ .... -- William A.
