Aide-memoire: installing EFS (read-only)on RedHat 8.0 Linux Distribution
cd /usr/src/linux-2.4.18-14
su
mv .config .config-original /* save copy of original config file, if any */
cp configs/kernel-2.4.18-athlon.config .config /* my machine is Athlon 800 */
vi .config
set EFS module to yes /* i.e. CONFIG_EFS_FS=y */
/* N.B. also check APIC setting is appropriate.
I needed to set it separately after running
into errors when compiling the kernel
*/
make dep
vi Makefile
EXTRAVERSION = -14custom-gyy-efs /* label custom kernel with EFS */
make
make modules
make modules_install
make install
cd /lib/modules
mkinitrd ./initrd-2.4.18-14custom-gyy-efs.img 2.4.18-14custom-gyy-efs
cp ./initrd-2.4.18-14custom-gyy-efs.img /boot
/* the above cp seems to be automatic */
/* INSPECT grub.conf */
# cat grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/hda6
# initrd /initrd-version.img
#boot=/dev/hda2
default=1
timeout=120
splashimage=(hd0,1)/grub/splash.xpm.gz

/* Again seems to be automatic */
reboot AND dmesg | grep EFS SHOULD GIVE
EFS: 1.0a - http://aeschi.ch.eu.org/efs/
REMEMBER TO MOUNT FILETYPE efs:
mount -t efs /dev/cdrom /mnt/cdrom
