dh-exec-install - Install (and possibly rename) files.
debian/default.conf => /etc/my-package/start.conf
[linux-any kfreebsd-any] some-arch-specific-file /usr/lib/foo/
Being a sub-command of dh-exec(1), this program must not be ran directly, but through dh-exec, which automatically runs all available sub-commands if run bare; or explicitly with dh-exec --with=install.
It is meant to be used for the dh_install(1) family of files, and those alone. If it finds that its input is not such a file, it will do nothing, but echo back the contents. For a ful list of recognised files, see the FILE TYPES section of this manual.
The purpose of the program is to extend dh_install(1)'s functionality, by allowing to specify a destination filename.
This can be accomplished by a special syntax: the " => " mark between a source and a destination means that the source file should be installed with the specified destination name.
For obvious reasons, the source must not be a wildcard, and the destination in this case must be a file, and not a directory.
See the FILTERING section of dh-exec(1) for more information about how lines are filtered. Any non-comment lines without a filter will be left alone.
Due to the way executable scripts are called from debhelper(1), there is no way to know what options were used for the original dh_install(1). This means, that the --sourcedir option of dh_install(1) will not work correctly when dh-exec-install is in use.
Internally, the renaming happens by creating a temporary directory under debian/tmp/, and copying (or moving, if the source was under debian/tmp/ to begin with) the file there, with the new name.
This is done this way to allow dh_install(1) to do the real copying, and allow its options to continue working, even when renaming is involved.
The temporary directory is put under debian/tmp so that it will be cleaned by dh_prep(1) when the clean target gets to run. Thus, no extra code is needed anywhere to clean up the renamed files.
The sub-command was introduced in dh-exec version 0.1. Support for dh_installmanpages(1) files were added in version 0.13.
