Unusually one can install those packages by just issuing:
|
||||
|
||||
```
|
||||
sudo yum install git createrepo rpm-build make wget rpmdevtools python-sh dialog rpm-sign
|
||||
```
|

sudo yum install git createrepo rpm-build make wget rpmdevtools python-sh dialog rpm-sign
|

|

The build system creates build environments in chroots and so no other packages are needed on the host. All files created by the build system are contained within the qubes-builder directory. The full build requires some 25GB of free space, so keep that in mind when deciding where to place this directory.
|
||||
|
||||
The build system is configured via builder.conf file -- one should copy the attached builder.conf.default, and modify it as needed, e.g.:
|
||||
|
||||
```
|
||||
cp builder.conf.default builder.conf
|
||||
# edit the builder.conf file and set the following variables:
|
||||
# (make sure to leave no spaces around '=' sign!)
|
||||
NO_SIGN=1
|
||||
|
||||
# As time of writing this, the default for Qubes 2 Dom0 is fc20
|
||||
# and VMs is fc20 so if you want to build Qubes 2
|
||||
DIST_DOM0=fc20
|
||||
DISTS_VM=fc20
|
||||
```
|
||||
cp example-configs/qubes-os-master.conf builder.conf
|
||||
# edit the builder.conf file and set the following variables:
|
||||
NO_SIGN=1
|
||||
|
||||
One additional useful requirement is that 'sudo root' work without any prompt, which is default on most distros (e.g. 'sudo bash' brings you the root shell without asking for any password). This is important as the builder needs to switch to root and then back to user several times during the build process.
|
||||
|
||||
Additionally, if building with signing enabled (so NO\_SIGN is not set), one must adjust \~/.rpmmacro file so that it point to the GPG key used for package signing, e.g.:
|
||||
|
||||
```
|
||||
%_signature gpg
|
||||
%_gpg_path /home/user/.gnupg
|
||||
%_gpg_name AC1BF9B3 # <-- Key ID used for signing
|
||||
```
|
||||
%_signature gpg
|
||||
%_gpg_path /home/user/.gnupg
|
||||
%_gpg_name AC1BF9B3 # <-- Key ID used for signing
|
||||
|
||||
It is also recommended to use an empty passphrase for the private key used for signing. Contrary to a popular belief, this doesn't affect your key or sources security -- if somebody compromised your system, then the game is over, whether you use additional passphrase for the key or not.
|
||||
|
||||
So, to build Qubes one would do:
|
||||
|
||||
```
|
||||
# Import the Qubes master key
|
||||
gpg --recv-keys 0x36879494
|
||||
|
||||
# Verify its fingerprint, set as 'trusted'.

|

make qubes
|
||||
|

# ... and then to build the ISO
|
||||
|
||||
make iso
|
||||
```
|

|

gpg --import qubes-developers-keys.asc

# ... and then to build the ISO
|
||||
|
||||
make iso
|
||||
|
||||
And this should produce a shiny new ISO.

Code verification keys management
|
||||
=================================
|
||||
|
||||
[QubesBuilder](/doc/QubesBuilder/) by default verifies signed tags on every downloaded code. Public keys used for that are stored in `keyrings/git`. By default Qubes developers' keys are imported automatically, but if you need some additional keys (for example your own), you can add them using:
|
||||
|
||||
```
|
||||
GNUPGHOME=$PWD/keyrings/git gpg --import /path/to/key.asc
|
||||
GNUPGHOME=$PWD/keyrings/git gpg --edit-key ID_OF_JUST_IMPORTED_KEY
|
||||
# here use "trust" command to set key fully or ultimately trusted - only those keys are accepted by QubesBuilder
|
||||
```
|
||||
GNUPGHOME=$PWD/keyrings/git gpg --import /path/to/key.asc
|
||||
GNUPGHOME=$PWD/keyrings/git gpg --edit-key ID_OF_JUST_IMPORTED_KEY
|
||||
# here use "trust" command to set key fully or ultimately trusted - only those keys are accepted by QubesBuilder
|
||||
|
||||
All Qubes developers' keys are signed by the Qubes Master Signing Key (which is set as ultimately trusted key), so are trusted automatically.
