>Description:
The way to create a new snapshot /fs/.snap/20260628 archiving
the current state of a file system /fs, and configure fss0 to
point at it, is:
fssconfig fss0 /fs /fs/.snap/20260628
The way to load an existing snapshot /fs/.snap/20260628
recovering a past state of the file system /fs is:
fssconfig fss0 /fs /fs/.snap/20260628
Yes, those are the same command.
This is confusing and error-prone: what operation we are
_trying_ to do should not depend on what files exist on disk.
When _creating_ a snapshot, fssconfig(8) should be able to
report an error if the file already exists.
When _loading_ a snapshot, fssconfig(8) should be able to
report an error if the file does not actually exist.
>How-To-Repeat:
try to use ffs fss snapshots (say that five times fast!)
>Fix:
Yes, please!
Perhaps we should have separate options like -C and -L for
`create' and `load'.
