Bug#219528: Random root tmpfs filesystem size.
When d-i boots, the /sbin/init shellscript present in rootskel mounts
the future tmpfs root filesystem with the following command :
mount -t shm shm mnt
Reading the kernel docs, it seems that the new name for shm is tmpfs (i
may be wrong). Furthermore, the default size limit for the filesystem
is 1/2 of the phisical memory available, which is a bit random for d-i.
(and wasn't enough for me, i got the root fs full while downloading
I think the limit should be set manually (as documented in
/usr/src/linux/Documentation/filesystems/tmpfs.txt), with something like :
mount -t tmpfs -o size=100M tmpfs mnt
It worked for me (using the netboot image -- i still got out of RAM, and
the menu was killed by the kernel, but I got a bit further ;)
Hope this helps,
