Dear Experts, Could someone enlighten me about the following file: /etc/subuid ? This file appears to be owned by "setup" package. This is CentOS 7 system, and until now these files if existed were never changed. Today I have added user quite routine way, by doing /usr/sbin/groupadd -g 4500 [username] /usr/sbin/useradd -g [username] -u 4500 -c "User Name, email at domain"

...used for in Linux, apart from searching on the web. (When > there are surprises like the one I had today, one does like to know > what this particular file is used for). > > > Thanks in advance for your answers.
