 This project intends to provide help for booting an alternative distribution on a LaCie NAS. An USB key is an attractive way to do that because it is rather non intrusive for the legacy OS and the hardware (no need to open a case). This project intends to provide help for booting an alternative distribution on a LaCie NAS.

An utility like tcpdump could provide useful debugging information. Perhaps you have plug the ethernet cable in the wrong slot, and the kernel assign an ip address to the other one.

   * rootfs not found: the SCSI device name for USB key depends on a lots of parameters. On the majority of LaCie products the kernel command line argument "''root=/dev/sda2''" should be correct. But possibly you will have to turn this into "''root=/dev/sdb2''".   * rootfs not found: the SCSI device name for USB key depends on a lots of parameters.
