This commit (apart from the cosmetic change to avoid using 'none') changes the use of ramfs into tmpfs. The reason for this is that ramfs usage can fill 100% of RAM and cannot be swapped out. While tmpfs can be swapped out and can be limited in size.
The size chosen is arbitrary, but taking into account the ATV1 hardware 5% of 256MB means 12MB and 20% means 50MB, considering we have swap this is not too drastic. For any larger system, these sizes are fine as well as we do not expect /var or /dev/shm to be filled completely. So worst case is covered, but not expected.
Because syslogd is not properly started its remote syslog support when klogd dumps its kernel ring buffer content to it, most of the kernel boot output is missing on the remote syslog server. By adding a small delay between syslogd and klogd, we are sure the messages are properly send to the remote syslog by syslogd.
Busybox free reports incorrectly the used and free memory on a system. Which makes it harder to understand and compare information from other sources.
In the same effort we add some other useful procps-ng tools, like pgrep, pkill, pmap, slabtop, vmstat and watch.
