setup-storage 1.6: return of the dreaded 'Cannot satisfy pre-depends'?

[Thomas Neumann]

Hello

setup-storage 1.5: LVM delete+create works
setup-storage 1.6: LVM delete+create broken

Can someone confirm this regression? I am pretty sure I haven't done some stupid mistake
(like using the wrong libraries) but an independent confirmation would be nice.


how to reproduce:

== preparation on fai-server ==

(clone repo & modify setup-storage to use the repo's libraries)
 mkdir /srv/fai/config/tools
 git clone https://github.com/faiproject/fai.git /srv/fai/config/tools/fai
 cp -a /srv/fai/config/tools/fai/bin/setup-storage /srv/fai/config/tools/setup-storage_git
 sed -i 's#/usr/share/fai/setup-storage/#/var/lib/fai/config/tools/fai/lib/setup-storage#' /srv/fai/config/tools/setup-storage_git

(create a sample disk config)
vi /srv/fai/config/disk_config/lvm_test
--------------- 8< --------------------------
disk_config sda
primary  -  4GiB  -  -

disk_config lvm
vg my_vg sda1
my_vg-root  -  1024  -  -
--------------- 8< --------------------------


== perform test on fai-client ==

 /var/lib/fai/config/tools/setup-storage_git -X -f /var/lib/fai/config/disk_config/lvm_test
 /var/lib/fai/config/tools/setup-storage_git -X -f /var/lib/fai/config/disk_config/lvm_test
 setup-storage -X -f /var/lib/fai/config/disk_config/lvm_test

The first cmd should execute fine
The second cmd should fail with "Cannot satisfy pre-depends"
The third cmd should execute fine (if it's setup-storage 1.5)
