[parted-devel] commit_to_os() and need for wait_for_dev_to_appear

[Curtis Gedak]

Recently I have noticed a new need arise on the parted mailing lists.  
This is the need for a "wait_for_dev_to_appear" feature.

Would it be prudent to add this functionality to libparted?
If not, then the users (scripts and programs) of parted and libparted 
will need to duplicate this functionality.

With parted-1.8.8 and earlier, there did not seem to be a need for this 
feature.  After commit_to_os() was called, both the kernel and the 
device entries would reflect the changes to the partition table.  It is 
possible that this was a side effect of the commit_to_os() function.  
Perhaps this would be a good candidate location to include the 
"wait_for_dev_to_appear" check?


Following are the posts that identify the need for "wait_for_dev_to_appear":
