Hi,
followed the books and rebuilt a kernel, and copied the new stuff into
/boot.
Updated /etc/lilo.conf and ran lilo.
However when I reboot it picks up the old kernel.
/etc/lilo.conf seems O.K.

*******************************************************************
I have copied the old kernel and initrd files to the *291203* files.
I have replaced vmlinuz-2 (See http://nuz-2.ora-code.com).4.18-3 with the new build (see different date and
size).
I have made a new initrd*.img file after copying in the new kernel.
As far as I can see the system should boot from the December 30th version.
However uname -v tells me the kernel was built on the 18th April.
I am also puzzled as to the function of the System.map and module-info
links - these are not mentioned in my kernel building instructions.
I am also puzzled by the presence of a 'vmlinux' file with execute
permissions (which both vmlinuz files do not have).
I have so far worked from 'Linux Complete' and 'Red Hat Linux Unleashed'
which more or less agree.
About to dig into some O'Reilly books.
I am currently baffled as I seem to have followed the correct steps and have
the new kernel in the /boot directory pointed at by /etc/lilo.cof.
It was so much easier with Unix, where you just booted a single file :-)
I have probably done something trivially foolish, but this is my first Linux
kernel build so I am wondering if the books have left out something vital.
TIA
