[SOLVED] /tmp files removed at boot

jorge.costa · 2011-09-20 12:47:40

Hi there,

I had been using /tmp as a tmpfs for a while, however I've lost precious work files on a couple of occasions - mostly because I'm stupid - by rebooting the laptop, prior to saving those files.

Now, after losing 6 hours work again I've decided to move /tmp out of tmpfs and just leave it as part of the / filesystems.
However it seems that arch likes to clean /tmp on boot, I've grep'ed and re'gredp around /etc and I can't find any entry that removes /tmp files on boot or shutdown.
Does anyone know where is this done ?

$ sudo pacman -Q | grep initscripts
initscripts 2011.07.3-1

got it :
/usr/lib/tmpfiles.d/arch.conf

Or place your files in /var/tmp that's not getting cleaned at boot.

Fix the problem where it exists, don't hack around it. /usr/lib/tmpfiles.d is not under your control and it will be overwritten on initscripts upgrade. If you want to use this broken solution, override arch.conf in /etc/tmpfiles.d/arch.conf. It's important that the file have the same name.

/etc/tmpfiles.d/arch.conf doesn't exist, what should it contain ?

and what's its purpose ?

hold on, found a scroogle post about it,
http://mailman.archlinux.org/pipermail/ … 01577.html

its something fairly new,

Much better solution imo: use $HOME/tmp instead of messing around in /
(added advantage of no risc of messing up your system by filling up / by accident)

/tmp and friends are really ment to be TEmPorary, so just don't put anything you want to keep in it.
