I haven't put /proc explicitly on my /etc/fstab since a long time ago, |
53 |
and everything seems to be working. However, I use systemd, which |
54 |
always mounts /proc with the default options, and only uses the entry |
55 |
in /etc/fstab (if present) to override the default options. In other |
56 |
words, systemd always mounts /proc, no matter if it's listed in |
57 |
/etc/fstab or not. |

I don't know what OpenRC does, but it would not surprise me that it's |
60 |
something similar. |
