when i install rockylinux 8.4 minimal and use Rocky-8.4-x86_64-minimal.iso image, the rsyslog service is not automatically installed, but when i use Rocky-8.4-x86_64-dvd1.iso image, everything is normal.
This is a known issue https://bugs.rockylinux.org/show_bug.cgi?id=14
Quoting @nazunalika :
CentOS nor RHEL have minimal images for 8.4. It is likely they have ran into the same issues we have and just don’t see a need to continue working on it. Release Engineering has not been able to resolve this issue as rsyslog is not in BaseOS and we do not believe it to be a blocker for general availability. We will still release the minimal image, as is, missing rsyslog. We do plan on re-spinning ISO’s in the future for secure boot kernels. We may or may not solve this issue by then.
With that being said, if someone from the community wants to attempt to solve this issue in the mean time, you are more than welcome to do so. Until then, the minimal image will not contain rsyslog. And if you require rsyslog immediately on install, please use the DVD ISO or a kickstart/network install.
thanks for your reply
