Bug#456154: debian-installer: amd64 re-boot fails due to missing /etc/crypttab
Package: debian-installer
Severity: important
Hi there,
while trying to install debian I encountered the problem that the
installed system was unbootable.
The setup I tried is a md setup with everything crypted except /boot
This was reproducible with debian-40r1-amd64-CD-1.iso and unofficial
netinst cd from kmuto (because of ICH9 chipset and e1000 support, my
disks/cdrom are detected properly with the official cd's)
Here is the way I tried to install
1) Partition the disks
/dev/sda1 => 256MB
/dev/sda2 => rest of disk
/dev/sdb1 => 256MB
/dev/sdb2 => rest of disk
2) Set partition type to raid autodetect for all of the above
3) Setup raids
/dev/md0 => [ sda1, sdb1 ]
/dev/md1 => [ sda2, sdb2 ]
4) Choose /dev/md0 as ext3 which should be mounted on /boot
5) Choose /dev/md1 as target for a crypted disk (refered as
/dev/mapper/crypt for the rest of this text)
6) Setup LVM with /dev/mapper/crypt as physical disk
vg00 => /dev/mapper/crypt
lvol-root 2GB /
lvol-swap 8GB swap
lvol-usr 8GB /usr
lvol-var 8G /var
lvol-home 16GB /home
7) Happily install debian on it. Works all fine until I try to boot
into the just installed system. There it hangs with (something
similiar to)
vg00-lvol-root not found
vg00-lvol-root not found
Waiting for root filesystem
until it drops into a busybox shell. Disks are detected before, since
I got the message from md that md1 is not synchronized.
Doing the same like above just change / to be on md0 instead of the
crypted volume the system boots at least into single user mode.
Examining the install I found out that there was only an empty
/etc/crypttab, adding the entry for /dev/md1 manually I could mount
all the devices and then the system boots normally.
>From above I conjecture that also the failed try with / on the crypted
device was due to a missing crypttab.
