Package: cryptsetup-initramfs
Version: 2:2.0.4-2
Severity: normal
Hi,
since I am using a keyscript to unlock my crypto devices, I need to use
the initramfs option on all my crypto devices. That includes the virtual
disks for the virtual machines running on the box. Naturally, those
crypto devices don't contain a file system that is recognized by the
get_fstype function sourced from /usr/share/initramfs-tools/scripts/functions
get_fstype ()
{
local FS FSTYPE FSSIZE RET
FS="${1}"
# blkid has a more complete list of file systems,
# but fstype is more robust
FSTYPE="unknown"
eval $(fstype "${FS}" 2> /dev/null)
if [ "$FSTYPE" = "unknown" ]; then
FSTYPE=$(blkid -o value -s TYPE "${FS}")
fi
RET=$?
if [ -z "${FSTYPE}" ]; then
FSTYPE="unknown"
fi
echo "${FSTYPE}"
return ${RET}
}
[30/5020]mh@fan:~ $ sudo /usr/lib/klibc/bin/fstype /dev/mapper/salida
FSTYPE=unknown
FSSIZE=0
[31/5021]mh@fan:~ $ sudo blkid -o value -s TYPE /dev/mapper/salida
[32/5022]mh@fan:~ $
This, in turn, causes
/usr/share/initramfs-tools/scripts/local-top/cryptroot to wrongly assume
that device unlocking was unsuccessful, removes the unlocked device and
starts over.
I am not sure how to solve this since the behavior of the new script
seems in order in most regular cases. Maybe there should be another
crypttab option like "dont-expect-fs" that disables this sanity check
for insane setups like mine.
Greetings
Marc
