| + | Before installing kernel you need to mount kernel proc, sys and dev filesystems inside of chroot: | ||
| <file># mount -o bind /proc /pld/proc | <file># mount -o bind /proc /pld/proc | ||
| Line 111: | Line 112: | ||
| # mount -o bind /dev /pld/dev | # mount -o bind /dev /pld/dev | ||
| </file> | </file> | ||
| + | |||
| + | You need to tell initrd generator which hardware driver is needed to access your rootfs filesystem | ||
| + | by setting scsi_hostadapter alias in **/etc/modprobe,d/modprobe.conf** (or any other file in that directory) | ||
| + | |||
| + | <file>alias scsi_hostadapter ahci</file> | ||
| + | |||
| + | **lspci -k** command run on rescuecd can help you to find a correct driver: | ||

| + | |||
| + | You can also install multiple different kernels. | ||
| + | |||
| + | By default kernel installation also generates initrd based on mounted /proc, /sys, /dev files and configured fstab, modprobe.conf and few others configuration files. generated initrd (which by default is initramfs cpio image) is saved in /boot. | ||
| + | |||
| + | If something fails or you want to regenerate initrd manually you can do it using: | ||
| + | |||
| + | <file>/sbin/geninitrd -v -f /boot/initd-XXX-Y.gz XXX-Y</file> | ||
| + | |||
| + | command. Real example: | ||
| + | |||
| + | <file>/sbin/geninitrd -v -f /boot/initd-4.20.3-1.gz 4.20.3-1</file> | ||
| + | |||
| + | //-v// option causes geninitrd to write additional information, so you can see if proper kernel modules are being installed into initrd. | ||
| + | If booting with new initrd fails you can use **debuginitrd** and **debuginitrd=sh** boot kernel cmdline options to debug the problem. | ||
