It's the tool that was used before dh_install existed. Its man page says: Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles. > what does "more diskspace" mean, however? kilobytes? terabytes? 100% of > the diskspace used by the files installed? 200%? The cost is 100% of the disk space used by the files being installed, if your filesystem doesn't support reflinks; or 0% if it does. dh_install does something similar to cp --reflink=auto debian/tmp/usr/bin/foo debian/foo-bin/usr/bin/foo whereas dh_movefiles is more like mv debian/tmp/usr/bin/foo debian/foo-bin/usr/bin/foo On btrfs and other reflink-capable filesystems, dh_install should be basically zero-cost, as a result of --reflink=auto. I'd personally only consider using dh_movefiles for the largest of "data" packages. Things like openarena-data and nexuiz-data (hundreds of MiB) are fine with dh_install, but 0ad-data (about 3 GiB) would maybe benefit? (But if I maintained 0ad-data, I'd probably still use dh_install, and just make sure that I built it on btrfs or another reflink-capable filesystem if time and space were a concern.) > "my" largest package was less than 100mb in size, which can be a bit annoying > for > uploads, but for diskspace during build, several gigabytes (or more) are > not uncommon, so I'm having a somewhat hard time imaginening that the > above is a relavant argument in most situations. If your package's total Installed-Size is 100M and we assume the compressed size is (say) 60M, then I would expect the build to need: quite a lot ./configure && make + 100M make install DESTDIR=debian/tmp + 100M dh_install + 60Mdh_builddeb At best, dh_movefiles saves you the second "+ 100M". smcv

"my" largest package was less than 100mb in size, which can be a bit annoying for uploads, but for diskspace during build, several gigabytes (or more) are not uncommon, so I'm having a somewhat hard time imaginening that the above is a relavant argument in most situations.

The drawback of dh_install is that it requires more diskspace to build than dh_movefiles but is less error prone. So unless your package is very large, it is safer to use dh_install. Cheers, -- Bill. Imagine a large red swirl here.

6.1.3. Multiple binary packages question
Regarding section 6.1.3. Multiple binary packages, the lyx source package is referenced. The lyx source package uses some shell commands to move files around in the rules file. Is this preferred to using debhelper .install files? Kristian Penno CEOS Pty Ltd kristian.pe...@ceos.com.au +61 3 9458 4955
