# One chmod, in a directory the operator's account does not own. It goes
|
|
# through a unit for the same reason owuivm-detach@ does: polkit is the
|
|
# check that already works for this operator, and a unix group would
|
|
# only take effect at their next login.
|
|
#
|
|
# Whether an image is frozen is the owner write bit and nothing else, so
|
|
# these two verbs are the whole mechanism and `ls -l` is the whole
|
|
# report. Neither will run while the machine is up - qemu already holds
|
|
# the file open, so a chmod then would change what the mode SAYS without
|
|
# changing anything about what is happening.
