Fedora Users — Re: ID Numbering in Group and Passwd

Aaaah, now i see what you're getting at :o) You explained it pretty well, I just didnt cotton on to the fact that you were using 60,000 as an arbitrary number. I spose we'll have to wait and see how the RFE goes - hopefully there is some sort of solution implemented whether its the high / low stuff or the uniqueness or something else Redhat come up with.

Some times I am not that good at explaining things.

I have added to the RFE taking your comments into account as you will
see.  I am reposting some of my comments here for the list.

I used 60,00 as an arbitrary number.  If Fedora can work with 2^32
GID's then change 60,000 to 2^32 and work from there.  It isn't a big
deal.

The idea is to search from high to low for GID's and low to high for
UID/GID combos.

This also minimizes any holes in the UID/GID mix unless users are deleted.

Thanks for the suggestion.
