[Fedora-packaging] commands under privileged users' path

Well, currently I am reviewing several reviewing requests and I asked a submitter to change user/group registration scriptlets according to http://fedoraproject.org/wiki/Packaging/UsersAndGroups and he/she changed as such. Then I noticed : %pre servers # Following the Wiki instructions ... getent group iceuser > /dev/null || groupadd -r iceuser <snip> Here "groupadd" (which is in Fedora under /usr/sbin) is used by only basename, not by full path. IMO this will cause a problem when "yum update" or "rpm -ivh" is done by normal users using "su -c" or "sudo" because normal users usually don't have /usr/sbin in their path. So I think that the following should be added to the wiki that commands which are under privileged users' path and not under normal users' path must be written with full path. Do you have any suggestions? Regards, Mamoru
