I would go d'accord with "Always consider using 'install' vs ...".
However I do not understand why one should "Always use install".
And everytime I ask about the reasons, I don't get an answer, so I ask here again.
I do understand that there are cases where using install is quite beneficial.
When you need to set certain permissions (other than read access, see below) or an
When you rename files and want to create folders at the same time.
However, I get the impression TUs try to force people into using "install" even when
it doesn't actually make things easier and even then this should be an optional
change, not a must.
I especially don't understand why "mkdir" is "evil".
One example where I don't like using install -D is when that would mean giving a
destination file name that is the same as the source file name, just to be able to use
install's "-D" switch to create directories. Typos in that redundancy are not reported
as errors and will create problems later on.
Or when install would do exactly the same as a corresponding "cp" line. In that case
it is up to personal preference, certainly no mistake.
The only thing that would break a cp without chmod for nearly all (non-executable)
files is a umask including 0004, which I would call a serious problem in the build
environment. However, makepkg forces an umask of 0022 anyways.
See also my statement in https://aur.archlinux.org/packages/picard-plugins/
In that case a merge request (to that package) was "taken hostage" to force
changing everything to "install".
I don't like the attitude of forcing volunteers to invest even more time when the
original change is perfectly fine. After all, that might keep people from contributing
the next time. And a merge request is not a personal request. It's a request that
helps making the AUR better altogether.
I might have taken that wrong, but the comment was posted right after the request.
The request wasn't accepted until a day later and after I changed the PKGBUILD to
This was not the first comment pushing me to use "install" in my PKGBUILDS, but I
still wait for actual reasons, other than personal preference.
Don't get me wrong. "install" is a valuable tool and it should be used in Makefiles
that install directly into the system (which makepkg is not) because of the reasons
explained in http://en.chys.info/2009/05/install-vs-cp-and-mmap/ (and possibly
umask problems) but I don't like when people pick on perfectly valid PKGBUILDs
because they have a "feel" that everybody should always be using "install".
It's not like package maintainers have too much time at their hands and are happy to
change them just because of personal preference of people that don't have to
maintain the package.
