The efivar Machine that was at 99% is now down to 16.1%
after removing the Windows and CDROM options. Don't know if it
was a delayed change.

Other machine was at 68%, but deleted Windows entries, since no
windows or the disk that was even in machine. After deletion and
reboot the used space increased instead of decreation to 85%??
But now it shows.

So, something had it drop from 85% to the 22.3%?
Don't know if someone knows more??
Thanks.
