ako imam image od kernela, ima li teoretske sanse da dobijem natrag odgovarajuce CONFIG_* ? recimo da mi je nesto jednom uspjelo, ali sam zabunom izbrisao conf fajl, i onda nakon toga nijednom nije prosao smoke test :(
bzImage -> .config

Moguće je , ali uz korišćenje određenih patch-ova , recimo ikconfig
Ikconfig je integrisan u Linux kernel od verzije 2.6.
Code:
│ CONFIG_IKCONFIG: │
│ │
│ This option enables the complete Linux kernel ".config" file │
│ contents, information on compiler used to build the kernel, │
│ kernel running when this kernel was built and kernel version │
│ from Makefile to be saved in the kernel. It provides documentation │
│ of which kernel options are used in a running kernel or in an │
│ on-disk kernel. This information can be extracted from the kernel │
│ image file with the script scripts/extract-ikconfig and used as │
│ input to rebuild the current kernel or to build another kernel. │
│ It can also be extracted from a running kernel by reading │
│ /proc/config.gz and /proc/config_built_with, if enabled (below). │
│ /proc/config.gz will list the configuration that was used │
│ to build the kernel and /proc/config_built_with will list │
│ information on the compiler and host machine that was used to │
│ build the kernel. │
