There is currently redhat and a rhel. It looks to me like people have been using them indiscriminately. Calling the Red Hat experts: are these tags synonyms? If there's a difference, please make it clear from the tag wikis, and retag mistagged questions. (The redhat tag wiki says it's about the company, but the questions are about the distribution.)
There's a similar split amongst suse: there's also opensuse. Is there enough difference between the two to warrant two different tags? (Possibly, after all we have centos alongside rhel.) If the two tags should be kept, would the SuSE experts in the audience please check that they are used consistently, and write a suse tag wiki that (tries to) direct askers to the correct tag.
Given the response: please synonym redhat into rhel.
When writing tag wikis for distributions, I suggest using a similar presentation as arch-linux, debian, ubuntu.
ubuntu
anddebian
?centos
andrhel
? actually I'm about 90% sureredhat
andrhel
should be synonyms.suse
in theory could refer to pre novell ownership./suse
should perhaps be renamed/sles
, if it's about “Seleste Linux”?sles
,sled
, andopensuse
currently.suse
was a distro that novell bought.novell
should be a tag synonym of the above?sles
andsled
but those 2 are toopensuse
asrhel
is tofedora
and I suspect many people would say those are quite different.
