[Buildroot] - Question: How to change safely /var/log --> /tmp in buildroot

[Maxim Kochetkov <fido_max@inbox.ru>]

1. You can implement your own skeleton (based on your current skeleton)
2. You can modify your target rootfs by rootfs-overlay (BR2_ROOTFS_OVERLAY)
3. You can modify your target rootfs by BR2_ROOTFS_POST_BUILD_SCRIPT

The easiest way is 2.
I would recommend you to create your own skeleton.
