And it isn't applied to the package.

Hello,
yes, PAGE_SIZE was one of my concerns too.
I just borrowed those few lines from karmic's resume script, assuming they were
correct.
In the meantime I got blkid source code and I made a small program which does
the same (check the device and prints the 'type' field) getting the page size
P.S. Thanks for the hint on the offset_option calculation!

Since I don't know very well, yet, how things work, I just modified my
mkinitramfs script in order to add that file too.
Then, I unpacked the new file created by mkinitramfs to make sure all the
relevant things were there (my binary and its required libs).
Apparently they are all there (after
I tried another way to check if there has been a hibernation or not.
I found useful the blkid utility (which is included already in the initramfs
image).
I may pass a device name as well as an offset to blkid to check the contents of
the device.
In turn, it prints various info but now I'm

Okay, so I've been taking a look into this as well in order to fix
hibernation on my system which uses TuxOnIce. My issue seems to be
related to the wait-for-root check returning swap rather than
tuxonice despite there being a tuxonice signature on it. Digging

I checked hibernate.c but I think it leads nowhere.
It doesn't even find my root partition, that means (as far as I can understand)
that it is executed far too early to succeed.
Coming back to the resume script in initramfstools, the piece of code
which used to work for me in karmic is this:

That basically defines the whole problem, as I understand it right now. From

About that false negative you pointed out, I think you are getting the
wrong idea. I never intended to remove the wait-for-root call. In my
proposed solution, the wait-for-root call stays, and *AFTER* that, it
unconditionally attempts a resume, without checking the output of wait-

Hi Scott,
I think the first couple of messages comes from the kernel.
kernel/power/hibernate.c seems to have that code.
It also seems to check for any hibernation image, it parses the resume
partition as well as the resume offset from the kernel command line but it
seems to check only for the

so I changed my '/usr/share/initramfs-tools/scripts/local-premount/resume' file

attached).

Right, this patch would appear to be trivially correct.

Hi Scott,
my swapfile has been created once for all, so unless files are moving by
themselves in the hard drive its offset should never change.
In any case, I checked it across reboots and it's always the same.
If I read a few sectors from the hard drive with 'dd' starting from that offset

wait-for-root simply waits for the block device to be available; that

Oh, sorry, you say you're using a swap file - in which case how do you
know that the offset of that file doesn't change between reboots - or
how do you know it's contiguous. We don't really support resume from
swap files at the moment.
