What happened:
run juicefs with non-root user, will show this error:

2022/04/21 02:48:42.565676 juicefs[7575] : open log file /var/log/juicefs.log: open /var/log/juicefs.log: permission denied [mount_unix.go:83]

What you expected to happen:
should not permission denied.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?

Environment:

• JuiceFS version (use juicefs --version) or Hadoop Java SDK version:
• Cloud provider or hardware configuration running JuiceFS:
• OS (e.g cat /etc/os-release):
• Kernel (e.g. uname -a):
• Object storage (cloud provider and region, or self maintained):
• Metadata engine info (version, cloud provider managed or self maintained):
• Network connectivity (JuiceFS to metadata engine, JuiceFS to object storage):
• Others:

It's because the user running JuiceFS doesn't have write permission in /var/log. Add --log <log_file> to use a permitted file, e.g. /tmp/juicefs.log

Better change the default log path when user is not root.

still have the Error message.
