cirros's Issues
def_size option in bin/bundle should be increased
Now, def_size has value 24m, but it is not enough for building fiinal image.
Image with installed samba weights ~75m, so this value must be bigger than that.
If this value is too small, we get error "no space left available".
first run of bundle after file tree build fails with ENOSPACE
output is like as follows:

nfs server does not respond if access is denied
@vponomaryov reported:
if access is not allowed to client, next thing appear:
[ 4182.497622] nfs: server 10.0.0.2 not responding, timed out
And it takes very long time until adding rule for access.
patch sudo-install-sudoers-so.patch is incompatible with latest buildroot
Patch was made for old make file "buildroot/package/sudo/sudo.mk" and is not compatible with latest one.
It will get patching error, if try patch.
built image dies in init: can't load library 'libtirpc.so.1'
Followed README on Ubuntu 14.04.3 LTS, then launched image in OpenStack Icehouse. The image failed to boot with this error:
/bin/sh: can't load library 'libtirpc.so.1'
I think I missed something in the buildroot config.

Does cirros enables any firewall？
I start a cirros vm on Openstack env. It is running an nc server on cirros vm:
sudo nc -p 8080 -l -s 10.10.1.246
Then I curl nc server inside the cirros vm:
$ curl 10.10.1.246:8080
The server inside cirros vm gets request, and works fine.
But when I curl the nc server from the outside world. the curl command hangs on there. The nc server inside cirros vm does not receive any request. (I can ping and ssh the cirros server from outside)
Therefore I suspect there is a firewall that block the cirros ports (8080)? but I am not sure and do not know how to disable the firewall. There is little document about cirros on the Internet.

unrealistic amount of RAM is needed for the image
Far too much RAM is needed to boot the image. Original Cirros / ubuntu service VM is fine with 64 megabytes of RAM, for our image the smallest power of two it boot with is 8, so the needed RAM is in between 128M and 256M.
The reason is that the initramfs image is almost identical to the root image and thus the whole thing is fitted to RAM on boot. In our case lot of stuff was added to the root image hence this follows...
how to run apache services used the cirros ?
i want to run apache services by cirros , beacuse it's a very small operation system.
Enabled nfsv4 requires libnfsidmap package that is absent in buildroot
Patch "nfs-utils-enable-nfsv4.patch" enables nfsv4, but nfsv4 requires package libnfsidmap in buildroot.
If we use this patch, we get error with absent dependent package while building buildroot for a given arch.
Need add additional option to samba config
Bug in Manila is valid for all images done for Generic driver: https://bugs.launchpad.net/manila/+bug/1370216
need add option "include = registry" to "global" section of samba config located in "/etc/samba/smb.conf" to be able to use shares configured via "net conf" utility.
Originaly reported by David Disseldorp for default ubuntu image for Manila.
