Thought it might be a 'bash'-ism problems, but switching shells from
'bash' to 'dash' and retrying made no apparent difference.

I looked at '/var/lib/dpkg/info/linux-base.postinst' where '$label_len' is set:

	% grep -nA 19 'my %filesystem_types' /var/lib/dpkg/info/linux-base.postinst
	{ ... not necessary to show this ... }

And:

	% egrep -n 'label.*filesystem_types' /var/lib/dpkg/info/linux-base.postinst
	1316:	my $label_len = $filesystem_types{$type}->{len};

I noticed there's no failsafe value should the answer be "none of the above".  My in-use
file systems are:

	% nocomment () { grep -v -e '^[[:space:]]*$\|^[[:space:]]*#.*$' $1 ; }
	% nocomment < /etc/fstab | expand | tr -s ' ' | cut -d ' ' -f 3 | sort -u | tr '\n' ' '; echo
	auto ext3 iso9660 none proc reiserfs swap umsdos usbfs vfat

That 'none' belongs to a 'bind' file system that lives on an 'ext3' partition:

	% grep mnt/arc /etc/fstab
	/dev/hdb5	/mnt/arc     ext3   defaults,relatime,user,rw			0	0
	/mnt/arc/tmp	/tmp	     none   bind

Tried commenting out the latter line, and rebooting.  Then tried installing again,
and it still failed the same way.  Drat.

HTH...
