Apart from the update which I now have installed and still have to be tested, I just like to point out a few things that might help improve the package.
On the update side, wouldn't it be better for pkgutils to check if there is already an exisiting .rpmmacros and .rpmrc, and have the option to review the changes if any? The same thing with mkrepo.
I do not know about the other packagers but I have an unconventional setup and do not have my /src folder right directly under my /home/archie. It is on a subfolder, which is the way I prefer.
It's not a big deal really but the updates prompt me to double check my setup and make sure that my configuration are still in place because I do not want my RPMS saved on other locations. I also noticed that mkrepo added the /home/archie/src URI and I already have one that I use and what was needed to be added was the i586, athlon and noarch section along with the x86_64.
I understand that it would take a lot of time to modify the script and I am not asking you nor anyone to change it. I am aware of it and I can make the appropriate adjustments on my end. I also understand that standardizing the build environment would have its advantages, especially to users starting to learn to package.
I am just pointing it out so maybe someday someone (hopefully Martin) would be able to further improve this already excellent tool.
