So Colin Percival has confirmed that there’s nothing special about EBS volumes.
Perhaps the error is because of my config.
This is my hardcoded_jsoncfg.
static char hardcoded_jsoncfg[] = "{\"net\": {\"cloner\": \"true\", \"method\":
\"dhcp\", \"type\": \"inet\", \"if\": \"xenif0\"}, \"cmdline\":
\"nginx_baked.xen -c /etc/conf/nginx.conf\", \"blk\": {\"fstype\": \"ufs\",
\"source\": \"etfs\", \"path\": \"blk0\", \"mountpoint\": \"/etc\"}}”;
Is there any other configuration that I can check that might be the cause of
why the EBS volume isn’t mounting?
This is my rumpbake.conf, the only modification I made was to add rumpfs_ext2fs
A further question, do you think it would make sense to add some code to
simple.c that when booting, lists the block devices and the file systems found
(equivalent to the Linux command df -T)? That way I can see what block devices
are found.
