As Rich already pointed out, just make /etc/mtab a symlink from |
| 15 |
/proc/self/mounts. If there is more mount points there than the ones |
| 16 |
you need, grep -v'd them. |
| 17 |
|
| 18 |
And just for completeness, systemd actually requires /etc/mtab as a |
| 19 |
link to /proc/self/mounts, so don't be surprised if software in the |
| 20 |
future in Linux just assumes that. |
