[SOLVED] xorriso -volid Text too long error from running archiso build

Hi,

I have created a custom ISO for Arch Linux using archiso that provides the base Arch Linux installation ISO, except with the tools required to connect to the Wi-Fi on laptops with Broadcom chips and here is its GitHub repository. The problem is that for a reason that completely escapes me whenever I run the build.sh script (using

./build.sh -v

) inside its archlive folder (which, along with the customrepo folder of this GitHub repository, I move to my /root directory when I try to build my custom ISO) I get the error:

[mkarchiso] INFO: Done!

In my own efforts to debug this problem I decided to see if there were any significant differences between my build.sh file and the default releng build.sh script, which I did by running:

sudo diff -u /usr/share/archiso/configs/releng/build.sh /root/archlive/build.sh > build.patch

(if you are wondering whether my releng directory is out of date because my archiso package is out-of-date, well it's not because I run

pacman -Syu --noconfirm

on an hourly basis). This build.patch file has these contents (which as you can see should only affect the name and label of the ISO):

--- /usr/share/archiso/configs/releng/build.sh	2016-06-01 08:31:01.000000000 +1000

+iso_label="ARCH_$(date +%Y%m)_${_gitcommit}"
 iso_version=$(date +%Y.%m.%d)

So I must admit I am rather confused as to what I need to do now.

Thanks for your time,
Brenton

Re: [SOLVED] xorriso -volid Text too long error from running archiso build

Hi,

the problem is that you try to squeeze 52 bytes into the ISO 9660
Volume ID, which can take only 32 bytes.
(See ECMA-119, 8.4.6 "Volume Identifier".)

I assume $iso_label gets used as parameter of xorrisofs option -V
(aka -volid). At least the error message matches the number of
40 $gitcommit bytes plus 12 bytes of "ARCH_201606_" (from
"ARCH_$(date +%Y%m)_").

You will have to substitute $gitcommit by something that is not
longer than 20 bytes. You may gain some room for more bytes by reducing
the length of "ARCH_201606_", but 32 is the absolute limit.

Have a nice day

Thomas

Thank you so very much! I have been struggling with this and similar ISO issues for months.
