Raspberry Pi 2: don't use md for /var/log

[kgadek]

Looking at most recent /etc/fstab for RPi2 and it's contents is:

/dev/mmcsd0s1   /boot/msdos msdosfs rw,noatime  0 0
/dev/mmcsd0s2a  /       ufs rw,noatime      1 1
md      /tmp        mfs rw,noatime,-s50m    0 0
md      /var/log    mfs rw,noatime,-s15m    0 0
md      /var/tmp    mfs rw,noatime,-s10m    0 0

Notably, /var/log is memory based. IMHO, this is bad.

Is there a reason to do this? If not, we could probably just drop this line and allow /var/log to live under root.

Generally, logging on devices like these isn't all that useful and will chew up the cells on the flash device, so we avoid it by putting it on a memory device by default.

Ok, for me logs are never to be lost. However, if the community wants ephemeral logs, let it be.

You might consider setting syslog up to log over the network to a server. That is what I do when I care about logs never being lost.

Thanks for the feedback though :)
