I and a friend are administrating a number of virtual machines, each one dedicated to some task in the overall system. When we need to administrate them, we typically log in as root, since the only time we log in to the machines are when we need to perform administrative tasks in them. We usually do not use sudo, since every command we do will typically be a sudo command.
We would prefer to keep our accounts separate on these machines, to give us separate .bash_history, see when the other one was last logged in, etc. To do that, we will need two accounts with full root permissions.
One method is to change our normal user accounts to have UID=0 GID=0, i.e. the same as root. The question is: Are there any gotchas (i.e. unexpected or non-obvious effects) having several user accounts with the same UID and GID (in particular the same as root)?
P.S. I asked this over at Superuser, but that only earned me a Tumbleweed badge, so I am trying here instead.
