Bug in 5.0.24_108355

Reported by: billR Owned by:
Priority: major Component: guest additions
Version: VirtualBox 5.0.24 Keywords: dracut
Cc: Guest type: Linux
Host type: Windows

Description (last modified by frank) (diff)

Tracked down failures to install guest additions on CentOS 7. Symptom was constant syslogs:

 dracut: Can't write to /boot/initramfs-: Directory /boot/initramfs- does not exist or is not accessible. 

Upon rebooting, the system would be unbootable and required a rescue disk.

problem is on line 1042 of

   for i in /lib/modules/*; do
        update_module_dependencies "${i#/lib/modules}"

running the following code illustrates the problem:

   # for i in /lib/modules/*; do
        echo update_module_dependencies "${i#/lib/modules}"
   update_module_dependencies /3.10.0-327.22.2.el7.x86_64

the correct code puts a trailing '/' after 'modules':

    for i in /lib/modules/*; do
        update_module_dependencies "${i#/lib/modules/}"

To workaround this bug, do the following:

(mount GuestAdditions CD Image, cd to top level of CDROM).

# sh ./

(errors - define the following shell function taken from the script)

# update_module_dependencies()
    depmod "${1}"
    test -d "/lib/modules/${1}/initrd" &&
        touch "/lib/modules/${1}/initrd/vboxvideo"
    test -n "${QUICKSETUP}" && return
    if type dracut >/dev/null 2>&1; then
        dracut -f "/boot/initramfs-${1}.img"
    elif type update-initramfs >/dev/null 2>&1; then
        update-initramfs -u -k "${1}"

# for i in /lib/modules/*; do
        update_module_dependencies "${i#/lib/modules/}"

(the following files seem to be leftover and prevent my system from booting, delete them).

# rm -rf /var/lib/VBoxGuestAdditions

On the whole this report looks very reasonable, except that there is no file "". The code you mention exists in other places, and your change seems to make sense, but where did you find that file?

confirmed the problem VB-5.1.0 and CentOS-7.7 fails with the default installation on CentOS-7 with /boot being read only to all, group and user # chmod u+w /boot and rerunning works. is supplied from the VBoxGuestAdditions.iso

Fix is part of VirtualBox 5.1 and will be also part of the next VirtualBox 5.0 maintenance release.
