Some ramdisks - as example those generated by dracut - does not unmount proc, sysfs and dev, but does a "mount --move" to the new root. The problem with this is the following logic in /lib64/rc/sh/init.sh: if [ -e /proc/uptime ]; then up="$(cat /proc/uptime)" sleep 1 if [ "$up" = "$(cat /proc/uptime)" ]; then eerror "You have cruft in /proc that should be deleted" else einfo "/proc is already mounted, skipping" mountproc=false fi fi This means that with a premounted /proc you do have a one seconds delay by default. Now I do not know what time-resolution that file is supposed to have (i.e. how often that files is supposed to carry a new value), or if there is another way to ask the kernel if this really is old files or a already mounted /proc. However on my system I had no problem running: -- id=0; while [ $((id++)) -ne 1000 ]; do up="$(cat /proc/uptime)" && \ sleep 0.01 && [ "$up" = "$(cat /proc/uptime)" ] && echo Broke && break; done -- without problems, but just changing the logic from "sleep 1" to "sleep 0.1" will shorten the boot nearly one second for dracut users. So is there a sound reason to have 1 second instead of 0.1 second or even 0.01 second?
