Is there any objections about this? xorriso is currently used by
archboot and works fine. Images generated looks good.
Will this still work with filesystem images that are over 4GiB?
The issue about you talk is with file size inside the filesystem (ISO
9660), (2^32 - 1 bytes = 4GiB minus one hair)
But we are using "level 3", so this limitation is not an issue, since
files bigger than 4GiB will use multi-extent feature, the new limit is
8TiB per file :)
Just for test, this is a proof of concept:
# mkdir /tmp/big-test
# cd /tmp/big-test
# for x in {1..5}; do dd if=/dev/urandom of=data${x}GiB bs=1M
count=$((x*2**10)) ; done
# md5sum data*> checksum.md5
# xorriso -as mkisofs -v -r -l -iso-level 3 -o ../trance.iso .
# mount ../trance.iso /mnt
# cd /mnt
# md5sum -c checksum.md5
data1GiB: OK
data2GiB: OK
data3GiB: OK
data4GiB: OK
data5GiB: OK
#
Ready to burn on blu-ray :P
Sounds good, this is actually relevant to me as I have an Arch-based
distribution that mounts an image with a size> 4GiB.
Cool. I know about lglive (you made a nice good work).
I ask to you, because some time ago you added UDF support. If it was
added only for this, as you can see, can be dropped.
Thanks for the feedback.
Indeed, it can be dropped then. Come to think of it, are there any plans
to use some kind of union fs like UnionMount (the linux kernel mainline
union fs) or aufs3 (linux 3 aufs) again in Archiso?
OK.
I some of these goes to mainline, maybe.
You know the history, every year appears a new kind of union
mount/filesystem, but is rejected for mainline. There is a new "promise"
for linux-3.2, but who knows...
