Description of problem: If you create multiple files to add modules into the initrd in /etc/dracut.conf.d, each containing their own add_drivers stanza, then the modules listed are incorrectly concatenated together Version-Release number of selected component (if applicable): dracut-033-359.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. create file /etc/dracut.conf.d/dmsnapshot.conf with contents add_drivers+="dm-snapshot" 2. create file /etc/dracut.conf.d/isofs.conf with contents add_drivers+="isofs" 3. run `dracut -f` Actual results: Fails with the following message " Failed to install module dm_snapshotisofs " You can see that the names of the 2 modules are concatenated together without a space to delimit them. Expected results: Initrd correctly builds with the required modules Additional info: work around is to include a space " " at the end of each add_drivers stanza so that when the strings are concatenated they are correctly delimited.
This is documented in the manpage: add_drivers+=" <kernel modules> " Specify a space-separated list of kernel modules to add to the initramfs. The kernel modules have to be specified without the ".ko" suffix.
It could be argued that the vmware-tools are providing "a space-separated list of kernel modules to add...." # cat /etc/dracut.conf.d/vmware-tools.conf add_drivers+="vmxnet3 vmw_pvscsi"
Since these config files are sourced as shell scripts, it is not possible to fix this. In the future we should move to arrays with: add_drivers+=(vmxnet3 vmw_pvscsi) but still /etc/dracut.conf.d/vmware-tools.conf would be broken then
ACK. Thanks Stuart. I've updated the subject of this bug to reflect its current focus. Do you want to follow up on the vmware-tools aspect? Let me know if I can assist with anything. Thanks, -John
Red Hat Enterprise Linux 7 shipped it's final minor release on September 29th, 2020. 7.9 was the last minor releases scheduled for RHEL 7. From intial triage it does not appear the remaining Bugzillas meet the inclusion criteria for Maintenance Phase 2 and will now be closed.
