This isn't exactly rocket science. The 202.3 objective only requires
»awareness«. IMHO this means:
– Candidates should know that there used to be a boot loader called LILO
that they may encounter on older systems.
– The main reason why LILO was replaced by GRUB is that GRUB is more
flexible. In particular, LILO locates the stuff it loads (kernels and
such) by means of explicit block lists, which makes it very susceptible
to breaking if anything about a kernel changes. GRUB, on the other hand,
can read most popular file systems and can locate kernels by name.
– The most important consequence is that when a new kernel is installed
on a LILO-based system, the »lilo« command must be run to update the
boot loader's block list(s). (Distributions usually take care of this,
but people who build their own kernels must remember it.)
– The main configuration file for LILO is called /etc/lilo.conf. This lists
general LILO options as well as the various kernels that a LILO
installation boots, with options. It is roughly equivalent to the GRUB
menu.lst or grub.conf file.
– When LILO runs, it will output the letters L, I, L, O, on the console
as it progresses. If only part of the sequence appears, then something
went wrong, and exactly what letters show up tell you (in general terms)
where.
In particular, the objective does NOT require intimate familiarity with the
content of /etc/lilo.conf. Teaching the bullet points above in a classroom
should take about 10 minutes, max. What's the big deal?
