Package: mount
Version: 2.25.2-6
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
1. create an entry in /etc/fstab as follows:
/home/testuser1 /chroots/testuser1/home/testuser1 bind defaults,bind 0 0
2. run multiple times following command:
mount /home/testuser1
3. run
mount
4. see the outcome - /home/testuser1 was mounted multiple times, instead of
quiting with error message "/home/testuser1 is already mounted"
* What exactly did you do (or not do) that was effective (or
ineffective)?
see above
* What was the outcome of this action?
the directory was mounted several times.
* What outcome did you expect instead?
the directory should be mounted only once and any further attempt should
produce an error "already mounted"
While normaly one will not mount the same directory several times - it does
occur when using Ansible to configure the system, as it is common to run the
same Ansible scripts (playbooks) multiple times which are supposed to be
idempotent (not to cause changes on multiple runs of the same script).
Thank you very much!
