Yes. Looking at commit 009d1397331a89413e2c5eead163cadb47ccdb4b, rpm executes the sysusers config before %triggerprein. The preinstall scriptlet still gets executed, but in this case it is a noop since the accounts already exist. > 2) > When does it run exactly? > It doesn't seem to be specified in the DNF transaction output, however > since it actually creates the user:group, it has to run before the > preinstall scriptlet. > So that suggests the sysusers is handled somewhere during pretrans maybe? > I mean the package contains files owned by the user:group, so I just > want to be sure the user:group is set when the package is actually > being installed. > > 3) > How much is it compatible with older releases? > I strive to maintain a solid level of compatibility between Fedora, > CentOS Stream and RHEL SPECfiles to minimize the cherry-picking effort > required. > Is it possible to switch to sysusers.d now, but making it work on any > of: Fedora 40, Fedora 41, RHEL 10 or RHEL 9? > Or would it be necessary to keep the RPM scriptlet logic conditionally > for older releases? The native rpm handling is only available in F42+. (Maybe it'll be backported, but it's a fairly significant change, so I doubt that.) There are some choices for compatibility: - keep the existing scriptlets, probably making them conditional - use %sysuser_create_compat as described in the Packaging Guidelines [0]. In F43+ this will be a noop [1]. Since the package already has a sysusers file, this is going to be just a few lines.
