The 'arcane' issue isn't so much per-process as it is knowing which program does what and how or if they interact in a way that affects your upper-level task. For example, I don't think it is very obvious what you have to do for common things like giving a dhcp address with an associated dns name to a specific device. Or maybe setting up a group of users with some special file system access, samba shares, web logins with group access for several different web apps, and an email group address. And as for tar flags, if you use it for backups, which one will make your restored system bootable? > mark "but then, I also spent decades as a programmer" Then maybe it makes sense for you for each program needed above to not do much in the way of integrating with the others. From the perspective of a user it can seem complicated. -- Les Mikesell lesmikesell at gmail.com
