Hi,
As the subject says, I accidentally removed the 'sync' system user. (If
you want to know how I got to do that, I just experimented with hosting
my own Firefox Sync server on a public CentOS 7 server.)
When I removed the user, here's what I got:
# userdel -r sync
userdel?: l'emplacement de bo?te aux lettres de sync
(/var/spool/mail/sync) n'a pas ?t? trouv?
userdel?: /sbin n'appartient pas ? sync, non supprim?
This was the exact moment I said: uh oh!
I logged in to another server, and here it is indeed:
# grep sync /etc/passwd
sync:x:5:0:sync:/sbin:/bin/sync
OK, so it looks I shot myself in the foot. I guess I could recreate that
user by issuing the following command:
# useradd -u 5 -g 0 -d /sbin/ -s /bin/sync sync
Since I'm not exactly sure and I wonder if I may have overlooked
something, I prefer to ask first before wrecking my system entirely.
Please correct me if I'm wrong.
Cheers,
Niki
