Using the quota command question

[Tim Champ]

Hello all.

Quick (hopefully) question - the man page for "quota" says it isn't 
recommended to do a "-f" when specifying a user.  Due to some issues 
that would take a while to explain, we will need to fix quite a few 
quotas on users as we "xfer" them to a new system.

Is this an outdated statement in the man page?  If not, what is the 
risk?  I'd hate to have to run "quota -f" across a server of many 
thousand users just to fix one.

Thanks for any help!
