[Virtual-pkg-base-maintainers] Bug#861927: How to change /proc mount options is undocumented

[Adam McKenna]

Package: base
Severity: normal

There is no documentation within the procps package or the wiki on how to
modify /proc mount options on Jessie.  There is no /proc entry in
/etc/fstab.

The correct way appears to be to add the /proc entry to fstab.  Please add
documentation that describes the official way to modify /proc mount options.

This will be especially important once /proc is being mounted with hidepid
by default, as a lot of users will probably want to know how to go back to
the old behavior.
