Bug#764174: new "_apt" owner not ready for shared mounts

[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

Package: apt
Version: 1.1~exp3
Severity: grave

# find /var/cache/apt/archives/ /var/lib/apt/lists/ -printf '%u %g\n'|sort|uniq -c
    254 119 nogroup
   2013 119 root
     13 root root

# grep _apt /etc/passwd
_apt:x:111:65534::/home/_apt:/bin/false

The problem is that those directories are shared filesystems.

The user and group numbers on one system don't match those on the
others.

It so happens that mine are on a "sneakernet".

I will do chown -R _apt:root /var/cache/apt/archives /var/lib/apt/lists
at boot as a workaround.

But then there is the more general case of e.g., NFS mounted filesystems.
