I’m currently sanding down some remaining rough edges with the Citrix Workspace client app. So far it works OK, but I’m dealing with some details now.
Installing the RPM package creates a new citrixlog user and group. It’s supposed to be a system user and group, but the packagers have done a bad job, so citrixlog gets a UID of 1001 (next available) and the corresponding group gets a GID of 1001. As a result, citrixlog shows up in SDDM. Meh.
I’m planning on changing that to something more sensible like 999 for the UID and the GID. But before doing that, I’d like to know: which UID/GID combination is safe to use, e. g. there’s no package/service/whatever that will create a system user/group with the same UID/GID combination?
Is there a way to know if the 999/999 (or 998/998 etc.) UID/GID pair will be taken up (or not) by some other preinstall script in some other package?
Back in the days when I used Slackware, the SlackBuilds team kept such a list for all third-party additions to the distribution. It’s still available (and maintained) here:
