"ATF_DFLAG_NOSAVM" is used to restrict PBS server to not write a value of attribute to db every time it is modified.
@mkaro I think what this means is that the attribute is not preserved in db upon modification but when server is going down at that time it gets serialized into database.
Now when server starts and if someone modifies the attribute and after some time server goes down abruptly then the modified value can not be recovered.
@vchlum Since this a new attribute on queue. PBS server in it's current form does not set any comment on queue by itself. What I meant was that if you can modify "Attribute is stored in the database." to something like "All modifications done to comment are not saved in database, it is only saved to db when PBS server shuts down"
I had a look at the code where we modify the queue attribute, Unfortunately I could not find any place where we check for this flag before saving the modified queue into the db. We just save all of the queue attributes as soon as one of them is modified.
