You can do `whymask Gnome 3.12` to get the entire GNOME 3.12 mask, piping it to `grep -v mask: > /etc/portage/package.unmask/gnome3` then allows you to quickly update your GNOME 3.12 unmask; if you want this to happen on sync, you can put this line in /etc/portage/postsync.d/gnome3 and make it executable such that it'll be ran after every sync. The magic trick here is that awk -vRS= "/.../" matches paragraphs; as the record separator is empty, it takes the blank lines. -- With kind regards, Tom Wijsman (TomWij) Gentoo Developer E-mail address : tom...@gentoo.org GPG Public Key : 6D34E57D GPG Fingerprint : C165 AF18 AB4C 400B C3D2 ABF0 95B2 1FCD 6D34 E57D
