make mount not fail if mp exists

[markus2330]

If someone tries to mount something that is mounted already, we should not fail. (If it would do exactly the same action)

Affected:

• [ ] mount (the script elektra-mount is basically already a workaround for it)
• [ ] global-mount see #1301 src/plugins/conditionals/README.md
• [ ] elektra-mountcan be removed then

Unclear:

• [ ] do we need an option to disable this behavior?

I have set the milestone to 0.8.21 because it should be part of LCDproc release.

We also need this feature for #1374 and #1663

[markus2330]

A simple way to implement that feature would be to have a -f option which cuts the mountpoint's config before doing the mount.

If this is not a good way, we should rather move this feature to 0.8.22.

With --strategy preserve this works now for normal mounts.

[markus2330]

@Chemin1 It would be great to have a fully working preserve strategy, so that this finally correctly works for mount and global-mount.

[markus2330]

Sorry, actually we need "--strategy unchanged". And this should also be default for mounting.

The strategy is actually very simple: It only succeeds if ours, theirs and base is the same.

I'll have to take a closer look at how that works, as I did not even know that mounting has strategies until now.

Looking at our, their and base: Is this related to the install-config-file script that we talked about? I mount a file and get the base and our version. I mount the same file again (this is now their) with strategy unchanged and the mount succeeds?

I'll have to take a closer look at how that works, as I did not even know that mounting has strategies until now.

Basically every tool that writes more than a single key (in this case merging is trivial) different strategies are useful. So also kdb shell would profit from having 3-way merging integrated.

Project would be together with #1322.

@flo91 Having idempotency in mounting would be essential.
