Hello. I have a problem with not enough space in Qubes dom0 system partition.
I am not able to reinstall QubesOS on other drive.
I am not able to make trusted backups and reallocate space on current drive at this time because I am idiot, but it is off-topic.
I see another solution, but I am not sure that it is possible.
I need to shrink reserved space for some templates.
For you understanding:
I use Windows10 StandaloneVM which System storage max size is 40.0 GB. Some time ago I used 35 GB, so reserved space in dom0 for this VM is increased to 40 GB. Now, only 20 GB in use in this VM but disk usage in dom0 for this VM is still 40 GB. So I need to decrease this value, no need to resize root.img volume.
Same problem in Gentoo template.
Any way to solve?
P.S. My English may be broken, sorry.
