Rolling your own kernel is really considered a last resort on CentOS/RHEL. It seems like a strange exercise to select for an RHEL SA course (IMHO). If you really want/need to do this then reading through http://wiki.centos.org/HowTos/Custom_Kernel may be a good idea. > sadly, at no time did that > exercise actually work, so i just want to ask a general question -- > should i, with a standard install of centos 5.5 with all of the > required development packages, be able to checkout the kernel source, > and build and boot a new kernel? If done properly, yes. However it's not like just any git-checked-out kernel+config will make you happy. > upon reflection, the issues might have to do with the fact that LVM > was in use and perhaps the initrd didn't have LVM support built in > but, again, i can't check that until later today at the earliest. ... LVM will be automatically added to the initrd by mkinitrd (assuming the kernel it tries to use has the required modules). /Peter -------------- next part -------------- A non-text attachment was scrubbed...
