So I just noticed something pretty annoying with Fedora’s man pages for /proc.
In most other distros, man 5 proc lists everything: status, stat, cmdline, etc.
On Fedora, that page is chopped up into dozens of smaller ones like proc_pid_stat, proc_pid_status, and so on, but there’s zero indication of this in man 5 proc itself.
I only found them because I went looking for the field order in /proc/*/stat and had to use an online man page to get it. Then I ran locate proc | grep man and found /usr/share/man/man5/proc_* entries, and sure enough, man 5 proc_pid_stat had what was missing.
If the base page is split, it really needs a note saying “see also proc_pid_*” or something. Otherwise it just looks like the page is missing information.
