Re: Adding MD5 to Image...
Sorry, my bad. Misunderstood.
I don't mean *ADD* it to an image, but simply REPORT it when the image is finished...
And example of what I do daily..:
mkisofs -J -R -V toolbox#0327 -v -split-output -o /usr/image/archive.iso -iso-level 3 -path-list /usr/image/filelist.out /usr/image/
[...]
Total translation table size: 0
Total rockridge attributes bytes: 68578
Total directory bytes: 0
Path table size(bytes): 10
Done with: The File(s) Block(s) 2290479
Writing: Ending Padblock Start Block 2290813
Done with: Ending Padblock Block(s) 150
Max brk space used 1dc784
2290963 extents written (4474 Mb)
Add the line like I have below to the output..
Chksum: 5b2b214d09a5d8a9ea35dc32614dedb7 /usr/image/archive.iso
So then scripts could grep out the chksum, and write it to an *.MD5 file at the same time the image is made...

On vinyl, Ashish Rangole was heard scratching:
Pardon me if I misunderstand you I wonder if it is possible to
add the checksum of a file to the file itself. Because mkisofs
creates iso image file, appending the md5 sum to the image
defeats the purpose of having a checksum (unless you want to
strip out the md5sum info from the image before calculating its md5sum).
Having said that it, may be feasible to add it to cdrecord etc.

Hey guys..
How hard would it be to have MKISOFS add a line after creating an
image that had the MD5 sum for that image? i.e. Something like:
Total translation table size: 0
Total rockridge attributes bytes: 268578
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 1dc784
ISO Chksum: a69def10...190F5
2290963 extents written (4474 Mb)
(I've seen a few(?) patches to have MKISOFS read/write individual
files IN the image against MD5's, but nothing for the whole image..)
Only reason I ask is that alot of dist's are given with MD5's..
Currently I have to create the iso (split-output) twice, first time to
the files, second time piping it to md5sum.
I know enough 'C' to see where it writes to the file, but not
enough to even try and mess with it. :)
Ideas? Thanks!
Mike.
