  • I’ll just quote the OpenWRT Wiki here, because I think half the comments here confuse mesh and roaming:

    Are you sure you want a mesh?

    If you are looking for a solution to enable your user devices to seamlessly roam from one access point to another in your home, you need 802.11r (roaming), not 802.11s.

    It is unfortunate that some manufacturers have used the word “Mesh” for marketing purposes to describe their non-standard, closed source, proprietary “roaming” functionality and this causes great confusion to many people when they enter the world of international standards and open source firmware for their network infrastructure.

    • The accepted standard for mesh networks is ieee802.11s.
    • The accepted standard for fast roaming of user devices is ieee802.11r.

    These are two completely unrelated standards.

  • I got three, they all seem to work on me, but sometimes I prefer one over the other for no clear reason.

    1. Counting my breath duration. Breath in at normal speed, count how long it is, then breath out slower than that by two or three counts.

    2. Force my thoughts to become disorganised. I do something like free association between concepts and pictures of the inner eye. Common starting point for me is a free flight over a hilly landscape, then random things, woods, trees, rocks, water whatever, I don’t try to control anything about the theme. If I start thinking coherently or about something concrete from my life, I just start again, with another nature scene.

    3. Imagine a calm scene. The suggested starting point I was told was floating on an air matteress in an alpine lake (helps that we know those around here, but I’m sure non-alpine lakes work too) and imagine the things you can see uphill as you drift around your axis.











  • Is it OK to simply dd the 128GB disk to the 32GB disk using count to stop after the 16GB partition was cloned?

    I think it would work, but it seems a little overcomplicated, you can just use the partition paths as if and of of dd directly, as long as the output partition is not smaller than the input partition. For example dd if=/dev/sdc1 of=/dev/sdd1 bs=4M status=progress

    Your method would also copy the partition table I suppose, which might be something you want under specific circumstances, but then it would be a little harder to get the count right, just taking the size of partition 1 would be wrong, because there is some space before it (where the partition table lives) and dd would start at 0. You’d need to add up the start position and the size of partition 1 instead.

    Personally I would prefer making a new partition table on the new eMCC, and create a target partition on it. Then you clone the content of the partition (i.e. the file system). This way the file system UUID will still be the same, and the fstab should still work because these days it usually refers to mounts by filesystem UUID in my experience.

    If you make the target partition larger than the source partition, and you intend to use the full partition going forward you will additionally need to resize the filesystem to fit the new larger partition, for example with resize2fs.
