Re: [gentoo-dev] dosym function in binary package ebuilds

Hi,

This is just how name resolution works on UNIX (see also: namei). If you 
start at /usr/bin/xxx, take it's parent (/usr/bin/), and then follow 
components of the link (../../opt/Signal/${MY_PN}) you get
/usr/bin/../../opt/Signal/${MY_PN}, collapsing those two parents 
(assuming they're also not links), you're left with /opt/Signal/${PN}. 
This is done so that these links act correct in roots (if one just did, 
e.g. /opt/Signal/${MY_PN}, and you were in a root, it'd refer to the 
hosts Signal install).

Hope that helps,
