I do it on several systems. Note that there is a bug in the current EL 7 version of grubby which causes the initrd line to not be added to the stanza of newly installed kernels. Always check /etc/grub.conf before rebooting to a newly installed kernel, particularly when doing so remotely. :-/ -- ======================================================================== Ian Pilcher arequipeno at gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ========================================================================
