Bug 420677 – net-misc/unison-{2.32,2.40} unable to call remote binary

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Michael Weber (RETIRED) 2012-06-11 12:11:37 UTC]

Afaik a regular system does not have an /usr/bin/unison binary (due to slotted installs).

If you connect to a remote station (both running Gentoo) it tries to call unison but fails due the missing file.

My quickfix was to symlink unison-2.32 to unison, but that's not handy for multiuser.

Is it possible to try for "unison-2.40" and then "unison" on the remote side (given local unison is unison-2.40)?

I did not find any hint for config values in ~/.unison/*.prf

you will need to run, for example,

eselect unison set 1

seems that we can run this from within a ebuild.

actually there is already a message to user to set this up

pkg_postinst() {
        elog "Unison now uses SLOTs, so you can specify servercmd=/usr/bin/unison-${SLOT}"
        elog "in your profile files to access exactly this version over ssh."
        elog "Or you can use 'eselect unison' to set the version."
}
