Package: cryptsetup
Version: 2:1.7.3-4
Severity: important
Tags: patch
Dear Maintainer,
I whould like to use skip and offset in /etc/crypttab for my root volume, but
those options are ignored by update-initramfs.
Ex crypttab:
cryptsda /dev/sda /etc/crypttab.conf/cryptsda.key
hash=plain,cipher=aes-cbc-essiv:sha256,size=256,offset=2048
should produce conf/conf.d/cryptroot in initramfs:
target=cryptsda,source=/dev/sda,rootdev,lvm=vg00-root,hash=plain,cipher=aes-cbc-essiv:sha256,size=256,offset=2048,keyscript=cat,key=/cryptroot-keyfiles/cryptsda.key
but generate:
target=cryptsda,source=/dev/sda,rootdev,lvm=vg00-root,hash=plain,cipher=aes-cbc-essiv:sha256,size=256,keyscript=cat,key=/cryptroot-keyfiles/cryptsda.key
It is part of BUG #714380, as a patch is provided, I created a seperat bug
report.
Regards
Pascal
