Re: Issue with s6-rc-update

[Paul Sopka]

Thank you for your quick answer!






So here ist the script, running s6-db-reload with strace:


#!/usr/bin/env execlineb

importas -S USER

define s6dir /home/${USER}/.local/share/s6-rc/
define s6live /run/${USER}/s6-rc/

backtick date { date +%s }
importas -Su date
define s6db ${date}_db

backtick s6dbOld { readlink -f ${s6dir}/compiled }
importas -Su s6dbOld

elglob -0 sources ${s6dir}src/*

foreground {
    s6-rc-compile -v2 ${s6dir}${s6db} ${sources}
}

foreground {
    strace -v -s256 s6-rc-update -v3 -l ${s6live} ${s6dir}${s6db}
}

Funnily enough, when I invoked s6-rc-update with strace by hand after a cold boot, it just... worked. Once I invoked the script (I have tried standalone s6-rc-update before, but probably only after invoking the script at least once), I have written, it did not work again. And here you have the pastbin of the output it produces: https://pastebin.com/zbsMybZK.

Thank you

It is probably just a mistake in my script, but I have quadruple checked it and can not find it. If that is case I am sorry to have bothered you.

s6-rc-update: fatal: unable to make new live directory in /run/${USER}/s6-rc:s6-rc-update:HgP5A0: No such file or directory

Where "...HgP5A0" is the old livedir, that is now gone, yet the symlink is still pointing at it.

 Hi Paul,

 This tells us that something went wrong in making the new livedir or
migrating the old one to the new one. It is weird that your old
livedir is gone: the migration is atomic, so if the symlink fails to
update, the old livedir should not be deleted. It is possible that you
have uncovered a bug in s6-rc-update.

 Can you strace -v -s256 your invocation of s6-rc-update, pastebin the
result, and give us a link? This will show exactly what is failing.

 Thanks,
