[gentoo-dev] dosym function in binary package ebuilds

[Fabulous Zhang Zheng]

Good evening, dear list

Most binary package ebuilds have such a *dosym* statement in src_install(),
take net-im/signal-desktop-bin as an example:

dosym ../../opt/Signal/${MY_PN} /usr/bin/${MY_PN}     (where the variable
is signal-desktop)

*dosym* creates a symlink of the binary under opt at /usr/bin/ according to
devmanaul.

I'm confused about the "../../", since S="${workdir}",  the correct way
seems to be "dosym  ./opt/Signal/xxx    /usr/bin/xxx"

It's much appreciated if anyone could help   ; )
