== Fields order ==
Some packages require the addition of system users. For them to be ignored by things such as lightdm, tthey have to be in the sub-1000 UID space. Looking at packages in ABS, these users are simply added with an <tt>useradd -u ...</tt>. However, there is no guideline or authoritative list that I can find which lists which UID is used for what, which is free, or how to register a UID for a specific system user. It would be nice to see a section about it here. --[[User:OlivierMehani|OlivierMehani]] 19:31, 13 October 2011 (EDT)

[[Arch_Packaging_Standards#Package_etiquette]] states: "It is common practice to preserve the order of the PKGBUILD fields as shown above." But this is not true. Common practice is to use {{ic|/usr/share/pacman/PKGBUILD.proto}} as a template, and the order of fields in that prototype has a far greater influence on packages in the wild than this page. This page should edited to reflect the current state of {{ic|PKGBUILD.proto}}. Perhaps this page should state: "It is common practice to order PKGBUILD fields so they match the order of fields in {{ic|PKGBUILD.proto}}.

* Package names should NOT be suffixed with the upstream major release version number (e.g. we don't want libfoo2 if upstream calls it libfoo v2.3.4) in case the library and its dependencies are expected to be able to keep using the most recent library version with each respective upstream release. However, for some software or dependencies, this can not be assumed. In the past this has been especially true for widget toolkits such as GTK and Qt. Software that depends on such toolkits can usually not be trivially ported to a new major version. As such, in cases where software can not trivially keep rolling alongside its dependencies, package names should carry the major version suffix (e.g. gtk2, gtk3, qt4, qt5). For cases where most dependencies can keep rolling along the newest release but some can't (for instance closed source that needs libpng12 or similar), a deprecated version of that package might be called libfoo1 while the current version is just libfoo.

== Is it acceptable for build() to start by removing directories? ==

I just downloaded a PKGBUILD whose build() function begins with the following:
 +
 
 +
find ./ -maxdepth 1 -mindepth 1 -type d  -exec rm -r {} \;
 +
 
 +
It seems to me that a PKGBUILD has no business doing this and that it is potentially dangerous. I admit that its danger will typically require people to do non-standard things and, arguably, things they would be better advised not to do anyway. But it still seems to me to invite trouble.

: I'd argue that this is an acceptable thing to do, at least in some cases. As an example, consider [http://www.talend.com/products/data-integration Talend Open Studio DI]: a single source file provides files for Windows, Linux, Mac OS, PowerPC (?) and Solaris. In response, the {{AUR|talend-open-studio-di}} PKGBUILD simply removes them. Does removing those files invite trouble? Yes. But removing files seems like an integral tool in the package maintainer's toolkit, and plenty of other weird stuff happens in PKGBUILDs too.
