cleaning /usr/obj before copying it to USB key

[Matthias Apitz]

Hi,

I build kernel and userland (out of SVN) and install in on an USB key
mounted as /mnt this way:

# cd /usr/src
...
# make installworld  DESTDIR=/mnt
# make installkernel DESTDIR=/mnt KERNCONF=GENERIC INSTALL_NODEBUG=t
# make distrib-dirs  DESTDIR=/mnt
# make distribution  DESTDIR=/mnt

To use the (booted) USB key later to install other laptops or netbooks I
enrich the key with /usr/src and /usr/obj as:

# cd /usr
# cp -Rp src /mnt/usr
# cp -Rp obj /mnt/usr

Having done this I can use the key just to install the system on the
laptop with the above DESTDIR=/mnt wherein /mnt is now the target root
of the laptop;

all this works just fine;

my problem is that the both 'cp -Rp ...' commands takes many hours (12
and six hours) because they are transferring a lot(!!!) of small files; I
have had a look into /usr/obj and it seems that after 'makeworld' and
'makekernel' there are left over a lot of temporary files from the build
processes...

is there a clean way to remove those files before 'cp -Rp obj /mnt/usr'
while the result is still useful for another make install with DESTDIR=/mnt ?

Thanks
