docs:geninitrd
This is an old revision of the document!
Initial ramdisk used mostly only to mount root filesystem.
Generation
Check available kernels (Example: section):
/boot]# geninitrd
Regenarete (adding -v to see details) as suggested in above examples:
/sbin/geninitrd -f --initrdfs=initramfs /boot/initrd-KERVER.gz KERVER
Debbugging
Getting shell just after initrd boot ends/fails: Edit '' /etc/sysconfig/system'' , set:
RUN_SULOGIN_ON_ERR=no
Add
debugrd=sh
to kernel boot options (by editing'' /boot/grub/grub.cfg'' or adding to GRUB_CMDLINE_LINUX_DEFAULT in /etc/sysconfig/grub and running update-grub)
Reboot. HINT: CTRL+PgUp/PgDown scrolls initrd logs.
