Doc Type: Bug Fix
Doc Text:
Previously, the vdsm-tool command would fail on certain actions when run as the root user. This was caused by the logic used by the vdsm-tool command, whereby 'sudo' would be added to actions requiring root privileges, causing those actions to fail. Now, the logic used in the vdsm-tool command has been revised so that 'sudo' is not added to actions when the vdsm-tool command is being run as the root user.

Description Alon Bar-Lev 2014-01-22 13:10:31 UTC
using sudo requires tty and other unwanted side effects if already running as root.

for example using vdsm-tool vdsm-id under root produces an error as sudo fails because of lack of tty.

unsure if there are other issues similar to this one.

see bug#1054759

Andrew, this fix doesn't enhance anything, it fixes a bug which caused by wrong execution of sudo statement. if user already root and we're adding "sudo" to the command we run, it requires specific configuration under /etc/sudoers which vdsm doesn't configure. the fix here just prevents this bug by not adding "sudo" if user is already root (which how vdsm-tool execute some commands, such as vdsm-id). only if running as vdsm user we configure specific sudoers entries for specific commands during vdsm installation.

thanks for filling the doc-text!
