man lilo
 -q     List  the currently mapped files.  lilo maintains a
        file, by default /boot/map, containing the name and
        location  of  the  kernel(s)  to boot.  This option
        will list the names therein.

/boot/map sa myslim vytvara, ked si lilo vytvara novu konfiguraciu podla
/etc/lilo.conf.

man klogd
KERNEL ADDRESS RESOLUTION
       klogd  will attempt to resolve kernel numeric addresses to
       their symbolic forms if a kernel symbol table is available
       at  execution  time.   A  symbol table may be specified by
       using the -k switch on the command line.  If a symbol file
       is  not  explicitly specified the following filenames will
       be tried:

       /boot/System.map
       /System.map
       /usr/src/linux/System.map

Nemusis dat make install a potom ani nastavovat INSTALL_PATH.
Namiesto toho ak pouzivas moduly:
 make modules modules_install

Potom skopiruj /usr/src/linux/arch/i386/boot/zImage tam kde mas jadra (napr.
/boot ) pod inym menom (mne sa osvedcilo zImage-2.0.30 alebo zImage-2.1.32).
To iste plati o System.map, potom ich moze klogd natahovat s volbou -k, s
tym, ze spravny subor si zisti prikazom uname -r.
Edituj /etc/lilo.conf a pridaj tam polozku pre nove jadro. (Ale zachovaj
stare.)
Spust /sbin/lilo.
A mozes rebootnut.

To vyzera tak, ze nevie najst System.map. (Teraz iba hadam.)
