greetings

if i do this in a script on a basic mail and web server setup

groupadd -g 55 nofiles
useradd -g nofiles -d /var/qmail/alias -s /sbin/nologin -p'*' -u 56 alias
useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' -u 57 qmaild
useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' -u 58 qmaill
useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' -u 59 qmailp
groupadd -g 60 qmail
useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' -u 61 qmailq
useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' -u 62 qmailr
useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' -u 63 qmails
groupadd -g 64 vchkpw
useradd -g vchkpw -d /home/vpopmail -s /sbin/nologin -p'*' -u 65 vpopmail

will i cause any problems with DEFAULT upstream provider package addons that
might use in the future that want to install with the same UID or GID
numbers??? again, by default?

it seems that between 55 and 70 is the small block of contiguous uid/gid
space in general

thanks and kind regards
