Re: qmail GID change

Dave,
I am a bit puzzled, I compiled qmail on one machine and transferred the
binaries to another machine with totally different UID's and GID's
than where I compiled it on.
Sorry, maybe I didn't explain the problem clearly, here is what I
have in my /etc/passwd file:
alias:x:7790:2108::/var/qmail/alias:/bin/true
qmaild:x:7791:2108::/var/qmail:/bin/true
qmaill:x:7792:2108::/var/qmail:/bin/true
qmailp:x:7793:2108::/var/qmail:/bin/true
qmailq:x:7794:2107::/var/qmail:/bin/true
qmailr:x:7795:2107::/var/qmail:/bin/true
qmails:x:7796:2107::/var/qmail:/bin/true
but I need to change gid's 2108 to 400 and 2107 to 401.

Can I just stop qmail, change the gid's in passwd file, chgrp the
files and restart qmail?
Thanks,

You can't do that.

No, you have to compile qmail on a system with the UIDs/GIDs as the
system you're going to run it on. You can temporarily change the
UIDs/GIDs on the build system to match the target system, then set
them back when you're done with the build.
