Problem with fai-cd and squashfs?

[Christian Meyer]

Hello there,

Knowing an elderly FAI version, I'm currently testing FAI 5.3.6 from
Debian Strech, so squashfs and dracut are new to me.

When booting a self-buid FAI-cd I shortly see an error message from
losetup in early boot:

starting version 232
...
dhcp: PREINIT eth0 up
dhcp: BOND setting eth0
RTNETLINK answers: File exists
losetup: /run/initramfs/squashfs/LiveOS/ext3fs.img: Warning: file does
not fit into a 512-byte sector; the end of the file will be ignored.
cat: /sys/class/net/eth0/name_assign_type: Invalid argument
cat: /sys/class/net/eth0/name_assign_type: Invalid argument
INIT: version 2.88 booting
...

Now FAI starts normally, but I have seen individual "SQUASHFS error"
messages, too.

Is this a bug or am I doing something wrong?
Why not creating an image with file-size of n*512 bytes?

BTW: I build the ISO with 'fai-cd -Mf /fai.iso' and dd'ed it to an USB
pendrive.
