[Solved] How do i apply a patch to embedded/nanobsd (read-only filesystem?)

[neglas]

I am trying to set up pfSense on a Compact Flash card. I have applied this patch to a VMware virtual machine running 1.2.2, using this command:

patch -p1 -d / < wildcards.patch

It works as expected.

Now I want to add the patch to an embedded version on a CF, but there seems to be a problem with writing permissions:

[1.2.3-RELEASE] [root@pfSense.local]/root(1): fetch http://cvstrac.pfsense.com/attach_get/132/wildcards.patch
fetch: wildcards.patch: open(): Read-only file system
[1.2.3-RELEASE] [root@pfSense.local]/root(2): pwd
/root
[1.2.3-RELEASE] [root@pfSense.local]/root(3): cd /tmp/
[1.2.3-RELEASE] [root@pfSense.local]/tmp(4): fetch http://cvstrac.pfsense.com/attach_get/132/wildcards.patch
wildcards.patch                               100% of   12 kB   56 kBps
[1.2.3-RELEASE] [root@pfSense.local]/tmp(5): patch -p1 -C -d / < wildcards.patch

Hmm...  Looks like a unified diff to me...

patch: **** can't find usr/local/www/services_dnsmasq_domainwildcard_edit.php

As you can see, I tried using /tmp instead of /root, but to no avail.

Is there a way to make this patch work on nanobsd/embedded?

Or is it maybe possible to patch the img file before writing it to the CF?

Start with the command:  /etc/rc.conf_mount_rw

And end with:  /etc/rc.conf_mount_ro

Cheers.

Thanks, that helped.
