Public bug reported:
I'm reporting this bug against util-linux, which seems to be the source
package for the affected packages related to the libuuid user:
* libuuid1
* uuid-runtime
Both of these packages manage the "libuuid" user. However, neither one
of the sets a shell for the user. From the postinst scripts for both:
$ grep useradd /var/lib/dpkg/info/libuuid1\:amd64.postinst
useradd -d /var/lib/libuuid -K UID_MIN=$FIRST_SYSTEM_UID -K
UID_MAX=$LAST_SYSTEM_UID -g libuuid libuuid
$ grep useradd /var/lib/dpkg/info/uuid-runtime.postinst
useradd -d /var/lib/libuuid -K UID_MIN=1 -K UID_MAX=499 -g libuuid libuuid
These postinst scripts should have a "-s /usr/sbin/nologin" (or
/bin/false), because this is clearly a "system" user - the home
directory is in /var/lib, and the UID/GID are set to a low range.
It would also be nice if the package included documentation that
indicates why this user is needed, and what purpose this directory
serves. I tried reading the util-linux source, but I couldn't find a
definitive answer to this.
