Description Aurelien Oudelet 2020-11-22 16:40:04 CET 
DrakX should not enable DM/LVM service by default after installation if not required.

When installing Mageia, if no dmraid/LVM device has been set, detected, found,
all services related to dmraid, lvm,... should be disabled.

List:
Name:                        STATE           VENDOR-PRESET
dmraid-activation.service    enabled         enabled
lvm2-monitor.service         enabled         enabled    
mdadm.service                alias           -            
mdmonitor-takeover.service   enabled         enabled      
mdmonitor.service            enabled         enabled

These unnecessary services should be disabled after installation.

Efficiency:
no more Bug 26901.
no delayed boot to look for what doesn't exist.

The installer only installs lvm2 if needed.
However some other packages might pull it as dependencies…
I've a local patch for that though, which I'll test

Comment 3 Aurelien Oudelet 2021-02-23 15:06:11 CET 
I am not against having tools like lvm2, dmraid installed.

I think that only matter is to have the minimum of service launched at boot time.
I do think a solution could be to only activate such services if they are required.

dmraid-activation.service    enabled         enabled
lvm2-monitor.service         enabled         enabled    
mdadm.service                alias           -            
mdmonitor-takeover.service   enabled         enabled      
mdmonitor.service            enabled         enabled

It could be done at installation time as the "resumé" of installation purposes a list of already activated service. Per administrator-basis (the user who installs Mageia) he can already deactivate such unnecessary services but this is beyond the scope of average user.

The test didn’t go as expected, or did you decide that, like Aurelien proposed, it would be better not to activate unneeded services?
