sendmail upgrade fails when mailnull user already exists
Last modified: 2008-05-01 11:37:56 EDT
I got an "execution of script failed" error when trying to upgrade to
sendmail-8.10.1-4. The culprit is the useradd line in the preinstall
script, which fails if the mailnull user already exists. The script needs
to cope with the possibility that the user already exists, e.g., because of
a previous sendmail installation.
