tmpfs /var/log/apt

[kozimodo]

Hi,

Following http://www.ubuntu-eee.com/wiki/index...ur_Flash_Drive, I added:

tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/log tmpfs defaults,noatime,mode=0755 0 0 
tmpfs /var/log/apt tmpfs defaults,noatime 0 0

to my /etc/fstab but /var/log/apt does not mount. Is there some configuration option that I'm missing? Will a "mkdir /var/log/apt" in rc.local do the same trick?

Thanks,
kozi

Rather than trying to mount a /var/log/apt as tmpfs, instead just create it in rc.local (which gets run after /var/log is mounted). Edit, /etc/rc.local and add the following to it:

mkdir /var/log/apt

That's what I use for what you are doing and it works fine.

Thanks. That is what I had already done. I guess I'm just puzzled since those fstab lines are suggested in numerous places so presumably it works on some installations.

I found those instructions too and it inspired me to mount a bunch of stuff as tmpfs for power savings reasons. However, as written, I don't think they can ever actually work because apt will always need /var/log/apt and it's doesn't seem to be keen on creating that directory when it doesn't exist. I would almost consider that an apt bug actually.

So what else do you mount to tmpfs to save power?

Just curious since I'm building a digital picture frame from an old dell and it would be nice to keep power consumption to a minimum.
