Re: [yocto] Make one directory writeable

You can use overlayfs for this. You mount the overlayfs on top of your rootfs and then it appear like you have a writeable file system. In reality all the new stuff is written to another (writeable) file system. If you dismount the overlayfs, the rootfs reverts back to its original state. If you

[yocto] Managing multiple builds

Hi, I've been struggling a bit with this question. I want to use Yocto to build two+ products with separate dev/prod images for each (dev including debug-tweaks, etc.). I've ruled out separate image recipes because my dev builds need ENABLE_UART on my RaspberryPi and that needs to be set at the con

As for the particular case of /mnt, on most images, /mnt is a symlink to /media, and /media is (on) a filesystem in RAM, so it's already writeable. If the write does not need to persist across reboots, use a tmpfs mount. If your real problem is that you cannot create anything in /mnt (or /media
