Bug#731806: debian-installer: FTBFS on sparc: genisoimage errors

[Cyril Brulebois <kibi@debian.org>]

Source: debian-installer
Version: 20131014
Severity: serious
Justification: FTBFS

Hi people,

(-sparc, -cd, genisoimage maintainers x-d-cc'd)

debian-installer 20131014 FTBFS'd on the buildd with:
| […]
| install -m 644 ./tmp/miniiso/boot_screens/notsupported.txt ./tmp/miniiso/cd_tree/boot
| install -m 644 boot/sparc/silo.conf ./tmp/miniiso/cd_tree/boot
| genisoimage -r -J -o ./tmp/miniiso/mini.iso -G /boot/isofs.b -B ... ./tmp/miniiso/cd_tree
| genisoimage: Error: './tmp/miniiso/cd_tree/boot/.' and './tmp/miniiso/cd_tree/boot/..' have the same ISO9660 name ''.
| Unable to sort directory ./tmp/miniiso/cd_tree/boot

Full build log:
  https://buildd.debian.org/status/fetch.php?pkg=debian-installer&arch=sparc&ver=20131014&stamp=1381835153

I can't tell for sure since it's been a while but I think I was unable
to reproduce it on a porterbox. Probably some FS-dependent fun? Anyone
would have a clue about it?

Thanks for your time.

Mraw,
KiBi.
