As Sean has mentioned recently, one known breakage that will result from switching from 2.6.22.5 to 2.6.24 is that some sysfs names change from *gta01* to *neo1973*. In particular, gta01-pm-gsm changes from neo1973-pm-gsm, requiring a new /etc/default/gsmd (this changed in the 2.6.24.x tree in revision 3649).
Now, I think this could be adequately addressed (in gsmd and elsewhere) by simply testing at run time which of the two possible directories is there, but perhaps there are more subtle dependencies in the rootfs that are harder to to resolve. The goal would be to make sure the next rootfs will work with 2.6.22.5 and 2.6.24, so in case someone needs to revert to 2.6.22.5 for some reason, that can be done without nasty side-effects. The changes are: old new --- --- gta01-button neo1973-button gta01-led neo1973-vibrator gta01-pm-bt neo1973-pm-bt gta01-pm-gps neo1973-pm-gps gta01-pm-gsm neo1973-pm-gsm Please let me know if user space can be easily prepared for this (maybe most of it is already ?), or if it will cause major upset. - Werner
