Iam on python 2.6 and Linux , I need  you inputs on how to ignore an
specific error when the mount fails


In general the mount has zero status if it succeeds and anon-zero exit
status if it fails.

1.But for one rare case the mount succeeds but returns anon-zero exit
status and when we get “Reading GUID from da0xxx: No such file or
directory” error , how to ignore this error and proceed with the above
code

2. Also need to add this check only for mount case i.e   mount
/filesystems  and not scanner_start

Any recommendations would be appreciated.

Regards,
Ganesh
