comment Mount /usr in RAM (loading from HDD when starting, and saving to when shutting down)
@ssokolow I think the answer would involve cgroups. But it won't necessarily make for a better user experience: you'll have some stuff being faster but other stuff will be slower.

comment VirtualBox 4.3.10 Clipboard Share Doesn't work on Ubuntu 14.04
I don't understand the question: you say “Addon and extension are installed”, and then you say that the solution is to “install addon”.

comment Can't get the shared clipboard to work on Ubuntu 14.04
The guest additions, which the asker has already installed, provide clipboard integration only in the GUI, which is explicitly not the point of this question.

comment .bashrc shebang line reports command not found
@AdrianPronk Some Windows software, maybe. But that isn't common, even in Windows I think, and definitely not outside Windows. Programs that don't care about encoding outside ASCII — which is most programming languages including shells — usually choke on U+FEFF, so editors should absolutely not go around inserting them. U+FEFF is a BOM only when it's the first character of a UTF-16 (or UCS-2 or UCS-4) stream, otherwise it's one of Unicode's many space characters.

comment Sudo is also user login password - why? how to change?
@evilsoup, kraxor: there is a security benefit to having a root password separate from the password for the ordinary account. User-level access is enough to cause damage (e.g. use the machine in a spambot or retrieve the user's financial data). However, an attacker who only has user-level access can plant spyware but can't really hide his tracks, whereas root-level access makes it easy to hide any trace of intrusion. There is no security benefit to sudo over su on a single-user machine (and only very limited benefit on a multi-user machine): it's about usability.

comment Sudo is also user login password - why? how to change?
@user68186 No: that thread explains the difference between sudo and su, but this question asks how to get su-like behavior out of sudo or how to use su instead of sudo.
