Oh man, checkinstall people already did it. Newest installwatch can divert installation to another directory. And if the script is modified a bit, it can even work with fakeroot (LD_PRELOAD=...:$LD_PRELOAD). Observe: mordae$ tar xf grep-2.5.3.tar.gz mordae$ cd grep-2.5.3 mordae$ ./configure --prefix=/usr mordae$ make -j3 mordae$ fakeroot mordae$ installwatch --root=$PWD --transl=yes --backup=no make install mordae$ tar czf grep-2.5.3.tgz -C TRANSL . mordae$ ls *.tgz grep-2.5.3.tgz mordae$ exit mordae$ tar tvf grep-2.5.3.tgz | tail -n 2 -rwxr-xr-x root/root 260309 2008-09-20 09:37 ./usr/bin/egrep -rwxr-xr-x root/root 152974 2008-09-20 09:37 ./usr/bin/fgrep mordae$ sudo tar xkf grep-2.5.3.tgz -C / # This can be wrapped to scripts, so user types: mordae$ divert -o grep-2.5.3.tgz make install mordae$ sudo merge -n grep-2.5.3.tgz ... Not overwriting /usr/bin/egrep Not overwriting /usr/bin/fgrep # Or even more: mordae$ package make install You will have package database, tarballs to deploy elsewhere and it won't be a bother. Merge script can convert root-owned files to bin-owned, but preserve device nodes and such.
