Obviously a reboot is required when loading a new kernel....
But
in general, does yum leave some breadcrumb clue that some other process
can check? For example, maybe there's something in the package files
that yum sees and creates a "/rebootRequired" file which is always
deleted upon booting?
If not, I think that'd be a cool idea.. the file could be
/rebootRequired.txt
and contain a plain text list of packages that caused the condition. :-)
Thanks
