Package: linux-base
Version: 2.6.34-1~experimental.2
Severity: minor

I had cdebootstrap generate a squeeze chroot, and installed a kernel
into it.  When I then ran "dpkg-reconfigure -a -plow" in the chroot,
this package borked the dpkg-reconfigure run because /etc/fstab
doesn't exist.

    + chroot cdebootstrap-amd64 dpkg-reconfigure -a -plow
    [...]

    No such file or directory at /var/lib/dpkg/info/linux-base.postinst line 1207, <STDIN> line 1.

This is an unusual case and I can work around it by creating an empty
fstab before running dpkg-reconfigure, but you might want to consider
adding a test for /etc/fstab's existence.

The above error messages are generated by initramfs-tools, not
linux-base.

There is such a test, and has been for some time.

Further, there is no filesystem call at line 1207 of the linux-base
postinst script, in the version you reported this on.   (It does
approximately correspond to the line in some earlier versions where
configuration files that need to be converted are opened.  But
configuration files aren't added to the list if they don't exist, so I
don't understand how this could occur unless one of those files was
deleted while you ran the postinst script.)

Once a job is fouled up, anything done to improve it makes it worse.
