[Pkg-sysvinit-devel] Bug#666696: initscripts: Default tmpfs size for /tmp is rather small on smaller systems

[Moray Allan]

Package: initscripts
Version: 2.88dsf-22
Severity: normal

Currently the default size of tmpfs for /tmp is 20% of RAM.  On smaller 
systems, this means that it's quite small.

Non-extreme example, with default setting of TMPFS_SIZE=20% in 
/etc/default/tmpfs:

$ free -h
             total       used       free     shared    buffers     cached
Mem:          500M       464M        36M         0B        10M       188M
-/+ buffers/cache:       265M       235M
Swap:         1.2G       2.2M       1.2G

$ df -h /tmp/
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           101M   24K  101M   1% /tmp

Advocates of tmpfs-for-/tmp talk about how the data will still get 
swapped out to disk if needed, so perhaps the default calculation should 
also take into account swap?
