 |
|
Hi, everydody!
After upgrading openrc to 0.11.8 I got strange message 'rm: can not remove «/run/openrc»: The file system is read-only' anytime at startup. How i can fix it ?
But system startup anyway is OK.
| Code: | OpenRC 0.11.8 is starting up Gentoo Linux (x86_64)
* /proc is already mounted
rm: can not remove «/run/openrc»: The file system is read-only
* Mounting /run ...
* /run/openrc: creating directory
* /run/lock: creating directory
* /run/lock: correcting owner
* /dev is already mounted
* Mounting /dev/shm ...
[ ok ]
* Mounting security filesystem ...
[ ok ]
* Mounting debug filesystem ...
[ ok ]
* Mounting cgroup filesystem ...
[ ok ]
* Starting udev ...
[ ok ]
* Populating /dev with existing devices through uevents ...
[ ok ]
* Waiting for uevents to be processed ...
[ ok ]

I hope for your help.

drhouse123,
Heres what happens.
/run is a mount point on the / filesystem. Before a tmfs is mounted at /run, it should be empty.
For some reason, yours isn't. So the message | Code: | | rm: can not remove «/run/openrc»: The file system is read-only |
is correct. root is still mounted read only.
Next | Code: | | * Mounting /run ... |
mounts /run as tmpfs over the top of whatever you have in /run, so it can't be seen any more.
You may not umount /run as it will be in use on your live system.
If you want to clear it out, you can boot with a liveCD, mount your / at /mnt/gentoo and look in /mnt/gentoo/run
There should be nothing there. Thats your real /run mount point without tmpfs mounted on top.
On a live system you can look with | Code: | | mount -o bind / /mnt/gentoo |
and you see the underlying run in the same place.
I have never felt comfortable with using a bind mount to manipulate the hidden filesytsem but it should work.
