Bug#375579: /scripts/local-top/lvm:28: sh: Syntax error: Bad substitution

[Florian Ragwitz <rafl@debian.org>]

Package: initramfs-tools
Version: 0.64
Severity: critical
Justification: breaks the whole system

Hello,

the changelog of version 0.65 of initramfs-tools says:

  * scripts/local-top/lvm: Be careful to activate volume group on lilo boot 
    too. Although in that case we don't know the precise volume group, we
    activate them all. Matches behaviour of previous hook.

This change seems to have introduced a bug in scripts/local-top/lvm on line 28
as it produces the following error message on boot:

  /scripts/local-top/lvm:28: sh: Syntax error: Bad substitution

which causes the boot process to fail on my box as the root filesystem will
never show up as it is on LVM, making the system unusable.

The erroneous line looks is:

  vg_lilo=${vg:0:2}

I'm not a good shell programmer, so I don't know whether this is a general
syntax error, a bashism that won't run on busybox or something else..


I downgraded initramfs-tools to 0.64 and regenerated the initrd files to work
this problem around for the moment.


TIA,
Flo
