In theory, maybe. In practice, it means that anything from the system that gets pulled into the initramfs that has been updated will also be included. That can lead to confusing issues when that kernel+initramfs combination was working, and now suddenly it doesn't because one of the userspace components is broken. If dracut grows a mode to only update the microcode, the we can probably look at that more closely. Otherwise, I'm not in favor for introducing multiple variables that could possibly change in the boot process. josh _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
