I began with debian in 1999. It was a 2 disk distribution of the first 
linux edition from the german "chip" magazine. Later I switched to Suse 
and the first update (I think from 6.2 to 6.3) messed up my system. I 
tried red hat but I got sick of all the rpm orgies. Then I decided to 
build the things mysef, now for more then 5 years. I use some chroot 
environments and a script driven build system on my master machine.
Right now Im fighting with an embeded installation of asterisk (ISDN- 
and internet phone box software) on an old K6-2/500 at 400-board.  :-)

Regarding your "15 seconds":
Put three disks with sizes of 200 to 300 GB and formated with reiserfs 
in your system an you will wait 20 to 30 seconds longer because of the 
filesystem consistency checks.

I can get a shell prompt after 5 seconds. The <10 seconds up to a 
picture include the firmware-loading of *two* FF-cards and the 
initialisation of a saa7134 mpex card.
