Get rid of underscores in filenames, use dashes instead.
This is first part of cleanup in filenames.
"qubes_rpc" still untouched - will be in separate commit.
No more ugly symlink creation at VM startup, nautilus-actions have system-wide
dir (in opposite to nautilus-scripts).
Currently old symlinks are not cleaned up. Maybe it should, but leaving them
have one advantage: will not break existing users behavior.
When /rw/home/user/.qubes-dispvm-customized is present use /rw/home/user
instead of default /etc/dispvm-dotfiles.tbz. Also make sure that /rw will not
remain mounted during DispVM creation.
The simplest way is just add proxy=... entry to /etc/yum.conf, but sometimes it
is reasonable to bypass the proxy. Some examples:
- usage of non-standard repos with some exotic file layout, which will be
blocked by the proxy
- usage of repos not-accessible via proxy (eg only via VPN stared in VpnVM)
This commit introduces 'yum-proxy-setup' pseudo-service, which can be
controlled via standard qvm-service or qubes-manager. When enabled - yum will
be configured at VM startup to use qubes proxy, otherwise - to connect directly
(proxy setting will be cleared).
