The legacy systems has UID numbers up until the low 2000s. In implementing a new user management system, I am looking into options to avoid UID collisions.One option is to just have a list of UIDs that cannot be re-assigned. I am currently looking into that.Another much easier option would be to use a higher range (3000+). Any concerns I should keep in mind?This would be on RHEL5, RHEL6 and RHEL7.
Any concerns with using high UID numbers (3000+) on RHEL5+?
