I used there the commit id derived from the UML linux exe as a suffix for gdb back trace files created during the bisect process. Sure - logic can be easily adapted and was in the mean while. But IMO it would be more stringent to have always the commit id presented in the version string for similar cases. > -- > Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org > > In personal conversations with technical people, I call myself a hacker.

You define your own versioning scheme if you build with CONFIG_LOCALVERSION_AUTO=n and define LOCALVERSION yourself. E.g. echo "-g$(git rev-parse --short HEAD)" >localversion-git or set it in kconfig or on the make commandline. Michal ^ permalink raw reply [flat|nested] 6+ messages in thread
