[SOLVED] AutoMounting of Partition Filesystems

On booting LE all the filesystems in the PC are mounted.

I want to set it so that only the two partitions it needs are mounted.

How is this best achieved?

Explanation: I run LE at present from a LiveUSB stick and plug it into various PCs.
I do not want any of the partitions in the PCs to be touched by LE.

Thank you.

Some variant of automount - Disable mount for internal HDDs - Ask Ubuntu should work. In LE you can't edit the embedded rules but if you create a new rule in /storage/.config/udev.rules.d/99-no-internal-drives.rules it will run last and should cancel out the earlier embedded rule as all udev rules in all udev rule files are loaded in sequence and evaluated cumulatively.

Thanks for the response.

That would mount all partitions in the PC during boot, and then unmount them again.

Not what I wanted to achieve ....... internal partitions not touched unless specifically directed by me.

I think it should be possible to unsquash the SYSTEM file, edit some rule and then mksquash again.
This would work?

I would need to know what options to use for the mksquash command and also what edit to apply to which file ..... maybe
/usr/lib/udev/rules.d/95-udevil-mount.rules ?

If this would work can you (or anyone else) provide the info needed?

Thanks.

I did some small tests ...... unsquashed the SYSTEM file (to unsquashed directory) and did mksquash on the directory again.

I seem to be missing something as the result from this command

mksquashfs unsquashed  livecd.sqfs  -no-xattrs

was very similar to the original file, except that the original reports

Number of ids 2

and the new file

Number of ids 1

Any ideas?

don't bother, just copy the file to where it is editable

Code

cp /usr/lib/udev/rules.d/95-udevil-mount.rules /storage/.config/udev.rules.d/

you'll probably want something like

Code

SUBSYSTEM=="block", GOTO="exit"

Putting a copy into /storage would mean, as I understand it, that the original settings will be applied first and then the copy, which would cause the partitions to be mounted and then maybe unmounted again.

Is this not the case?

Thanks for the edit suggestion, I hope to try it soon by editing the file in the squashfs file.

Quote from lrusak

no if the file has the same name it will override the original

Ah! Thank you.

I probably placed the above line in an incorrect position in the file, but the result was that I had no partitions auto mounted on boot up, but also I could not find a means to locate and mount any partition I might need, except on the network of course. I successfully mounted a network partition.

All I want to achieve is not to have the partitions mounted, but to have their presence recognised and have them made available for mounting through the filemanager.

Is it achievable?

Nope. What's wrong with having them mounted?

I have the OS on a USB stick which is nicely portable.
It is bootable on most hardware.

That hardware is not necessarily mine ..... and even if it was ....... I do not want unintended mounting of partitions in that hardware, but rather only mount a partition if a need arises.

The only thing you could really do is create systemd automount services, but this isn't really a good solution.

I couldn't do it in any case, as I know nothing of systemd

I will keep looking for alternatives, thanks

Thanks, but I could not make that work for me ......... I want no partition to be mounted automatically, but retain the capability of mounting any partition found.
