Protect against clashing mounts on the same machine #1

Closed HenrikBengtsson closed 2 years ago

HenrikBengtsson commented 2 years ago

If multiple job scripts run on the same machine and they mount the same folder, the first script that unlimited this folder will break the mount point for the other processes.

[x] The simplest solution to protect against this is to make all paths specific to the parent PID

Updated so that the temporary root folder is unique to calling process:

$ echo "PID=$$"

$ easycatfs config
mount_root=/tmp/alice/ppid=15187

$ easycatfs config
mount_root=/tmp/alice/ppid=15187
