vboxdrv.sh@ 76408

Last change on this file since 76408 was 72817, checked in by vboxsync, 6 years ago
Installer/Linux: sync the filesystem after running depmod. Hopefully works around the issue with zero length modules.dep files when a R0 bug in VirtualBox leads to lock-up when trying to run a VM (which happens very quickly in automated testing) straight after install.
