Implementation in OpenWrt. The flash.layout article documents how OpenWrt uses both SquashFS and JFFS2 filesystems combined into one filesystem by overlayfs. The kernel is also stored separately from these partitions in raw flash. When the kernel is built, it is also compressed with LZMA and gzip, as documented in imagebuilder .

I have had OpenWrt routers running for a year without this problem. I would recommend find what is logging to /tmp, and disable it, rather than removing the /tmp tmpfs mount. 1
