01:19 < bananapie> without using a named pipe, can virt-sparsify output to stdout instead of a file?
01:20 < bananapie> called from a bash script*
01:43 < bananapie> if I use a named pipe, it says 'Could not refresh total sector count: Operation not permitted'
02:33 < bananapie> ok. I found the answer, virt-sparsify doesn't read linearly, so named pipes doesn't work :(
No.
However, for copying mode (not --inplace), the longer answer is it
could be modified to make it work:
