Yesterday evening I investigated in detail why this was failing. It
failed for two reasons:
1)
On the host where world and kernel have been compiled the sources and
resulting obj files have been in
/home/guru/head/src
/home/guru/head/obj
and MAKEOBJDIRPREFIX=/home/guru/head/obj was used; later both trees have
been copied over to the USB stick to
/mnt/home/guru/head/src
/mnt/home/guru/head/obj
with the idea that when this was booted the trees would be again like
the original ones /home/....; and the same MAKEOBJDIRPREFIX would make
the "make installworld" (...) happy again; but not, it failed; the
installer was unable to locate the obj files and wanted to run
compilation again; the reason for this was
that on the original host /home was a symlink:
# ls -l /home
lrwxr-xr-x 1 root wheel 8 28 abr 11:06 /home -> usr/home
while this was not the same on the USB system; after changing this the
installer could find the objects;
2)
But then a 2nd problem showed up: for the first time I copied "src"
and "obj" to the USB stick with rsync(1) this way
# cd /home/guru/head/
# rsync -av -q --cvs-exclude src /mnt/home/guru/head/
# rsync -av -q --cvs-exclude obj /mnt/home/guru/head/
in the past I have used always the cp(1) command this way:
# cp -Rp src /mnt/home/guru/head/
# cp -Rp obj /mnt/home/guru/head/
I wanted to use rsync(1) with --cvs-exclude to not copy over all the .svn/....
files to the USB key; but silently this failed and a lot of files and
dirs have been missing on the target directory tree; until now I have no
idea why :-(
Any hints?
