Hello,
I'm running an updated wheezy and today faced with this little
problematic.
While running Midnight Commander to open (on-the-fly decompression for
browsing the archive) the kernel source package (a ~75 MiB .tar.bz2 file)
I got this error:

My Atom based netbook is not a powerful system but has 2 GiB of ram and
250 hard disk so, what was happening?
"df -H" told me:

Okay, so /tmp is full. Fine. I know how to solve it but I can foresee
more situations like this in the future so some questions arise. As the
current tmpfs default settings for /tmp seem a bit "unrealistic" (just %
20 of the RAM?) for even doing common tasks:
1/ How many room should be set for a "/tmp" partition? I never had it one
so I can't make any good estimation.
on my laptop my /tmp partition is about 225 Mb:
1] most of the time it is empty (right now only 1% is used);
2] I have a huge /scratch partition that is used when the /tmp
is not big enough;
3] I guess that the relevant size depends on what kind of file is used on fly (read, uncompress, compress, write, ...).
2/ Would be better to simply disable tmpfs for "/tmp"? This is how I've
been doing all these years.
I guess the /tmp mounted on a partition of /dev/sda is better idea than tmpfs one.
(having a sepated partion for /tmp is good idea.)
Any comments are welcome :-)
My 2 cents,
Jerome
