How to configure proxy for the overlay

Please customize the proxy variable in /etc/layman/layman.cfg

 proxy  : http://[user:pass@]www.my-proxy.org:3128

If unset, layman will use the http_proxy environment variable. To use this method:

 cd /etc/env.d
 sudo touch 99local
 sudo nano 99local

and please add:

 http_proxy="http://YourProxyAddress:YourProxyPortNumber"
 https_proxy="http://YourProxyAddress:YourProxyPortNumber"
 ftp_proxy="http://YourProxyAddress:YourProxyPortNumber"

And then to apply changes to the system:

 sudo env-update && source /etc/profile

To check this variable:

 sudo echo $http_proxy

and then:

 git config --global http.proxy $http_proxy
 layman -S

If you use a local proxy such as CNTLM to authenticate through a corporate proxy server or for whatever other reason, you should be aware that you may experience a several minute delay in GIT making the first connection to the proxy. This could be caused by GIT/cURL resolving localhost to an IPv6 address first ::1 and trying to connect to that before timing out (in my case, after 2.5 minutes). After the timeout, cURL will then try the IPv4 version of 127.0.0.1. If your local proxy only listens on the IPv4 address (which seems a common occurrence), make sure you define the proxy as such:

 git config http.proxy http://127.0.0.1:8080

To troubleshoot problems with your proxy, you can set the following environment variables:

 set GIT_TRACE=1
 set GIT_CURL_VERBOSE=1

Then run the command again and you will get much more information about what GIT and the cURL library are up to.

Restrict Thunar from showing encrypted partitions

For some reason, Thunar will sometimes show encrypted partitions as removable devices. To restrict thunar from showing encrypted partitions:

nano /etc/udev/rules.d/99-hide-disks.rules

and add:

KERNEL=="sda3", ENV{UDISKS_IGNORE}="1"

where sda3 is an encrypted partition meant to hide. Then use this command (as root) to trigger a refresh:

udevadm trigger

Unable to compile a kernel module
* ERROR: sys-kernel/spl-0.6.2-r3::gentoo failed:
* ERROR: sys-fs/zfs-kmod-0.6.2-r3::gentoo failed:

then do the same thing:

ls -l /usr/src/linux
lrwxrwxrwx 1 root root 12 Dec 25 07:50 /usr/src/linux -> /usr/src/linux-3.9.9-pentoo
cd /usr/src/linux

assuming /usr/src/linux links to the 3.9.9-pentoo sources,

zcat /proc/config.gz > .config
make clean && make clean
make prepare
make modules_prepare

Upgrading

Uninstall all blocks manually. For example:

emerge -C dev-lang/vala
