Everything I encountered that haven't worked:Not supported hardware by manufacturerNvidia Drivers with Wayland
I recently passed Linux Foundation System Admin and they had a weird Debian that just slapped me with man not found or something like thisI like it, but I think proprietary can tell it too.
I recently passed my Sys Admin cert from Linux Foundation and 50% of things by me were done on the fly:View to what website the cerficate has been issuedGit commiting and pushingSmart finding and deleting / movingNFS and SSHFS mountingFirewall redirection probably using iptablesOverall user managementDocker container managementSysctl kernel parameters persistenceSystemctl server managingAppArmor which I failedLVM disk extendingFrom source compilation using makeNTP time synchronisationthat's all I remember. Overall I find that typicall Linux Desktop differs from these certs and the job.
