Hi all

This morning I experienced something weird: my iohyve snapshots for RancherOS are listed in one of my iocage jails:

Code:
root@openVPN:/dev/zvol/vol0/iohyve/RancherOS # ll
total 0

I don't understand why they are listed in /dev and what the "c" file type is? And why my jail is seeing parts outside of the jail, which I find somewhat worrying.

This only happened shortly after upgrading from 11.2U7 to 11.3-Release and I only noticed because my AIDE-script noticed changes in the file system. The same folder exists on the base system, but only for this exact iohyve folder, not for iocage (both of which on vol0). I only have one mount point for the openVPN jail, which has got nothing to do with the /dev folder. I have two recursive snapshot tasks for the entire vol0 containing iohyve and iocage.

vol0 looks as follows :
