I am confused then. You said
|
||||
|
||||
> it does detect a crippled FS when run as root here.
|
||||
|
||||
which I took as the indication that on any FS if ran as root annex would detect it as \"crippled\" since then user (root) has ability to change even read only files/directories (thus removal was to demonstrate ability to overcome permissions protection). Was I wrong?
|
||||
|
||||
Here is redone script which instead of removing augments the file... and again annex doesn't consider file system crippled while I can augment file inplace
